PowerMac G4 MDD - HD video playback?

I have been searching for a bedroom computer to plug into my TV recently, and the mirrored drive door PowerMac G4 caught my eye on eBay the other day. Would these machines in particular be capable of playing HD (720p or 1080p) video stored on the built-in hard drive? Would I find good HD video performance when using the Mac's DVI output connected to a TV's HDMI?
I'm by no means a Mac newbie, but just not familiar with these G4 machines, so feel free to give me more technical responses! ;P

If this MDD model is the 1.25 Ghz single CPU, dual 1.25 GHz CPU or the 1.42 Ghz CPU model, it may be able to just barely deal with 720p video content.
My old single 1.25 GHz model could handle most, but not all 720p video. Even with a change to a ATI X800XT, 256 VRAM Graphics card, some 720p video was still an issue for me.
Forget about viewing any 1080p video content. It is not going to happen in any G4 model Mac.

PowerMac G4 MDD Video Capture Help

Hello, I have in my possession a B&W PowerMac G3 tower that is the educational AV edition that includes the Xclaim VR Pro PCI graphics card/capture card. It works only under OS9 and using Apple Video Player application. When I am done recording via either the Svideo or Composite ports (the only input ports on it), it encodes super slow, as it is a G3 at 350MHZ. This is just background information to what I need help with.
Anyway, I also own a PowerMac G4 MDD dual 1.0GHZ that runs OS 9.2.2 and 10.4.11 on separate hard drives. I wanted to speed up the video capture so I popped the Xclaim VR Pro into the top PCI slot of my MDD and removed the current Radeon 9000 Pro in the AGP slot (only when recording). I installed the latest ATI drivers for both cards here: Gona
So the the video capture works fine, but my main problem here is that I can't keep the audio input to stay on Line In, so it records sound. I can click Line In, but as soon as I let go of the mouse, it reverts back to None. Very frustrating. I would use the Apple Video Player application if I had it, but aperantly MDD's version of OS 9.2.2 does not include it. Can someone help me please? I appreciate any input on this matter. Please do not suggest that I buy a new Mac or a different capture device, as I am not looking to do that if I dont have to. Thank you.

I used to have an XClaim VR 128 card. I will try to look around for software on the web. In the meantime, here's an excerpt from a page on xlr8yourmac.com. I hope it helps.
OS 9.1 manages audio input differently than previous OS versions. This seems to prevent some applications (including Apple's own Apple Video Player) from changing the source.
For SoundEdit to record, I find I have to set the input source using either the control strip or the control panel BEFORE I launch the program. I also can't seem to get the "Recording Options" dialog to come up (nothing happens when I select the menu option), but since I don't use the program regularly, I may just be doing something wrong.
(reply)
try booting with a clean OS 9.1 install and set the audio source prior to running SoundEdit.
Several other readers noted they also had SoundEdit problems in OS9.1. (Some later wrote to say this did not solve their problems.)

Installing Leopard 10.5.1 on PowerMac G4 MDD

I have a PowerMac G4 MDD dual processor 1.25 Ghz, 1.024 GB Ram, with 115 GB internal Apple issued hard drive. The ram, keyboard and mouse are Apple original issue.
I am running Mac OS X 10.2.1 (6R73) on the original hard drive.
I am attempting to install Leopard 10.5.1 from an Apple DVD. (The Family 5 pack license) and have not been successful despite many attempts.
The Apple Studio display is connected to an Apple issued video card. The Mac came with an Ultra SCSI card. I removed it.
I installed a new Seagate Barracuda 320 GB ATA/6 7200 RPM 3.5 16 MB on the same buss as the original hard drive. I did not move the original hard drive from its original position. The Seagate hard drive jumpers are set to Cable Select. This drive would not accept installation of Mac OS 10.5. It also would not Verify or Repair. “Invalid B-Tree Header” was an unrepairable error. I exchanged that drive for another identically rated drive, and began again.
I verified the 10.5.1 install disk media twice. No error messages. Visual inspection of disk shows some minor scuffs, but they were on the disk when received. The disk package was sealed.
I have formatted the target drive using Apple Disk Utility--the Mac OS 10.2.1. compatible version. It has passed the Verify routine many times.
I have run the “Install New System and the “Erase and Install” many times.
I have run a CD/DVD lens cleaning disk once. No help.
System preferences set to Never sleep. Screen saver turned off. Not connected to any network during install attempts.
No other PCI cards or any other modifications to the machine.
I created a new Administrator account, logged in and attempted an install. Install failed. Error message: Cannot validate “BaseSystem’ package.
On some install attempts, some files were written to the target hard drive but not enough to constitute a functional system “Install Failed” message appears after about 2-4 minutes.
On other attempts, the install would hang in less than 2-4 minutes.
I have an identical PowerMac G4 MDD dual processor 1.25 Ghz, 1.024 GB Ram, with 115 GB internal hard drive on which the 10.5 DVD Leopard disk installed on an identical Seagate 320 GB hard drive on the first attempt. Both G4’s were purchased new on the same date from the same retailer.
The only differences between my two G4 MDD’s are:
1. that the problem G4 is running 10.2.1 on the original hard drive, and the working G4 is running 10.2.8 on the original hard drive. (I am not attempting to install 10.5 on that drive.)
2. that before installing 10.5.1, I moved the original 115 GB hard drive on the successful G4 to the slower buss and put two Seagate 320 GB drives on the faster buss previously occupied only by the original 115 GB hard drive.
3. I have not checked to see if the ram chips on the two G4’s are exactly identical manufacture, etc. Also have not compared every detail in System Profiler to determine if build number, etc. are identical.
To test the effect of drive position on the problem G4 MDD, I moved the original 115 MB hard drive to the slower buss, and put the Seagate target drive in the Master position on the faster buss cable. An Erase and Install attempt failed. Error message: “The installer could not verify the ‘BaseSystem’ package. Three folders were installed on this attempt. “BaseSystem.pkg.152.Mrqnl2” of zero KB, “Library” of zero KB, and “private” of 64 MB. On a previous attempt, the BaseSystem folder was about 292 Mb.
Sorry this is so long but I wanted to avoid the first thirty questions clarifying things I missed.
I would appreciate your help. Thanks.

Not having a firewire cable at hand, I transplanted the target drive to the successful install G4 so that I was installing on the successful G4 using a "successful CD/DVD drive" on to the target Seagate Drive. WORKED the first attempt.
Believing that the knowledge gained by these tedious exercises in troubleshooting should be shared and added to the public record, the following should be noted.
Clearly, either the problem G4 MDD has a problem, or the CD/DVD drive in the G4 MDD has a problem with installing Mac OS 10.5. A gambler would bet on the CD/DVD drive having some issue and not the Mac G4.
It is noteworthy that the CD/DVD drive in question has successfully read and burned CD's and verified the Mac OS 10.5 Install DVD without error, hence, in all of those actions, indicated no error or problems at all, yet, appears to be the problem. Perhaps INSTALL of Mac OS 10.5 raises some issue with the CD/DVD drive that the other successful actions (reading and burning of CD's) does not raise. I have no other reasonable explanation.
My complimentary Apple Care for my purchase of a family pack Leopard 10.5 treatment was that since I was not installing 10.5 on my "main drive" any help was outside my Apple Care coverage. (The subject drive was on the Master position of the fastest ATA cable, and to my non-technical, dumb lawyer approach to things, was the "Main Drive.)
Of course, a prudent person would install a new operating system on a clean drive without trashing (and jeopardizing) a working operating system (and the data on that drive) until certain that the new operating system was fully functional and non-destructive, before switching to the new operating system. That concept appears outside the scope of complimentary AppleCare. Even more relavant, given comments in the Apple knowledge base about the disasterous consequences of interrupting an install.
Thank you to Eustice who was precisely on track as near as we will probably ever know.
I have spent nearly 8 days messing with this,(well spent)and, read nearly 1,000 questions and replies on various forums on other issues beyond this which have solved many questions I have not posted. To all of the true giants of technical genius who have helped me and so many others in this forum, THANK YOU.

Exrended Desktop in Tiger/PowerMac G4 MDD

Hi, I just made the switch full time into OSX, running Tiger 10.4.3. Previously I was running 9.2 and switching into OSX 10.2 as needed. I was running an extra monitor with an extended desktop for my pallettes, etc that worked in both systems. Now in 10.4 I am not even given the option to extended the desktop in displays, nor does it detect anything when "Detect Display" is clicked. The big question is Why doesn;t it work?, but in light of that could it be the extra video card is no longer compatable perhaps? I'd really like to get the extended desktop back.
iBook 900 (14) 9.2/PowerMac G4 MDD 10.4 Mac OS X (10.4.3)

Just to add if the computer has an old OS installed (older than the version that shipped with the MDD), I guess it's possible the drive lacks full support at the OS level. Like Dave says, I expect it's just the jumper settings and changing them from cable select to master should get the drive working. If the drive still can't be used when burning discs via the OS disc burner and iTunes etc though, it may be an OS/application problem. Third party applications like Toast etc should still work though.

Video playback so sluggish on eMac 1GHz G4

Just installed Mac OS X 10.5 clean to newly formatted drive. Has 768MB of RAM and enough hard drive space.
Getting to the desktop, it feels sluggish.
IE and webpages load slowly (that's relative , I guess).
But what is surprising is that video playback (eg, WMP or AVI file) is so choppy. Using either QT or VLC, all are so sluggish.
I take the same video files and run it on a PC laptop (abeit much faster 2GHz Core 2 Duo, etc... so not a fair comparison, I know).. and it is smooth, as expected.
What could be wrong? Is Mac OS X 10.5 too much for this old eMac?

You exceed the min CPU requirements for OS 10.5 Leopard.
It's RAM where you are sorely lacking.
Even though the min. RAM spec for 10.5 Leopard is 512 MBs of RAM.
768 is no where near enough.
If your eMac only has USB 1.0 ports, you can install a max of 1.0 GB of RAM.
If your eMac has USB 2.0 ports, you can install a max of 2 GBs of RAM.
IF your eMac is the newer USB 2.0 model just install the 2 GBS of RAM.
New iterations of OS X use more and more system resources and the more RAM, the better OS X runs.
Video streaming and playback is another issue.
Older PowerMacs can't handle the new modern video codecs that much newer Macs can handle more easily.
If the video is in 360 or 480p it should play and stream fairly fine with little to no issues.
YouTube, QuickTime, MP4s, AVI files encoded in 360 or 480p should stream with the right video software.
WMP files will be problematic on any Mac and maybe you'll need to hunt for a video player that works in OS 10.5 to be able to playback WMP files.
You maybe able to stream and or download/play 720p videos but these will be choppy and have a noticeable amount of frame drop. 1080p videos will not stream or play at all from direct on the eMac.

Is it possible to output 1080 to a 50" LG Plasma from a PowerMac G4 MDD?

PowerMac G4 MDD Dual 1Ghz
1.5GB Ram
AGP GeForce 4MX
OSX 10.2.8
LG 50PY3DF (50" LG Plasma)
I work in a video department and recently got new Mac Pros leaving us with some spare G4's. We're looking into having one of the G4s replace the old iMac in the studio and connect it to the 50" LG Plasma to display HD Graphics/Video. Currently we have an older iMac connected to it through a scan converter displaying at it's highest resolution which is low, so the image isnt good on the plasma.
I've looked into 2 cards for the G4, the ATI Radeon 9600 Pro and 9800 Pro, so that I could then output from DVI to HDMI. They both support 1920x1080 (9600 @ 150hz and the 9800 @ 120hz for analog monitors).
Does the analog refresh rate differ from a plasma refresh rate? The LG accepts 1920x1080 60hz at RGB/HDMI-PC, 1920x1080 75hz RGB-PC, and 1920x1080 24-60hz HDMI-DTV.
Any Ideas? Thanks

Hi,
Well, you have me scratching my head, that's a real puzzle.
Try an Open Firmware re-set, do the 're-set all' procedure:
http://docs.info.apple.com/article.html?artnum=42642
BTW, ATI (and OWC) has just released this info on their 9600 video card, meaning it's not so good for G4's:
Knowledge Base
ATI Customer Care > Product Information > Specifications, Features, Comparisons >
737-21888: Radeon 9600 PRO PC & MAC Edition list of supported system configurations

PowerMac G4 MDD power button flashes but doesn't boot

My PowerMac G4 MDD will not boot when the power button is pressed. The power button lights up for about 1/2 second and then goes out. There are no noises at all. No hard drive spin-up, and no fan.
For the past few years, in order to get the machine to boot up, it has been necessary to unplug it from the power source and plug it in again. I have read about other people having this same exact problem and remedy. Now, however, doing the unplug/replug thing no longer gets the machine to boot. The power button will light up briefly only after an unplug/replug. Subsequent pushes will not cause it to light up until another unplug/replug is done.
I have removed all peripherals, including the video card (only card that was in the machine), 3 of the 4 RAM modules, disconnected the hard drive and DVD drive power cables, and disconnected the fan, and removed the PRAM battery (which I know is probably dead), and this makes no difference in the behavior: The power button lights up for about 1/2 second and nothing more. I also disconnected and reconnected the power supply cable to the motherboard. No difference.
There seem to be 2 possibilities: I need to get a new PRAM battery and press the PMU reset button, or my power supply has gone bad.
Before I buy a PRAM battery, I am investigating the power supply to see if I can tell whether it is good or not. Some people with similar problems have discovered blown fuses in their power supplies. Before I open up my power supply and look for that fuse, I have a question for anyone who had that fuse problem: Did your power button still light up, even briefly, when your power supply had the blown fuse?
Best regards,
Dave

Improving quality of streaming video playback

Here's my system:
PowerMac G4/450 Sawtooth tower, upgraded to dual 450 mhz processor
1 GB RAM
ATI Radeon 9800 pro 128 MB video card (modded version)
OS Tiger 10.4.11
Online video playback from sites like YouTube, Hulu, etc. is choppy. It's not too bad. Probably only a few frames short. But, it is noticeable, and I'd like to improve it. I've played around with some of the settings in the ATI Display Preferences, but haven't been able to get it to look any better. Anyone have any suggestions? I was thinking I might have to upgrade the CPU to something faster, but would like to avoid that if possible. Also, if it matters, I only have the G4 connected via S-video to a TV. That's it. (And one more thing - I have a broadband Internet connection, and the other computers that share the connection have no problems with video streaming, so I'm pretty sure it's not a lack-of-bandwidth issue.)

Just to clarify, you don't mean because the computer was originally a single 450, do you? 'Cause it was upgraded to a dual 450 at some point in the past. (I picked up the computer used.) I figured I'd probably have to do another upgradeto the processor to fix the problem. But if the fact that the machine was originally a single 450 is always going to hold it back, then there's no reason to upgrade again.

Can't hear recorded sound during video playback

I take a lot of videos of my kids. I have noticed lately that the volume is low or muffled...you can't hear what is being said even if they are screaming 6 inches away. I thought maybe something had gotten into the microphone, etc. I recorded a voice memo and on playback i could hear what was recorded just fine at a normal level. Now once I tried to record a video of my kids talking, it played back so low that i can't hear anything and that is with the volume turned wide open. Not really sure what this issue could be but if the volume works fine on voice memo wouldn't it work the same on video playback?

ITunes / Windows Video Playback.. (what, you actualy want to WATCH vid's?)

I'm sure there are several people out there that are having the same or similar problems, but because I can't seem to find them with the exact problem I'm having, I thought a new thread would be appropriate....
Upgraded from 6 to 7 yesterday... music seems to play OK (not as good as 6, but not all the issues other people are having). Now video playback in iTunes is little more than a slideshow with audio to (almost) match.
When I go to play back any vid podcast, or other video in my library for that matter, iTunes bumps my processor up to 100% and holds it there, and the video does little more than skip and bounce through the entire playback (even if the overlay controls go away fully, the slightest mouse movement brings them back). The audio quality seems to almost follow the video, but they get away from each other (the audio was about 2 seconds ahead of the video/slide show while watching the current version of Photoshop TV). Any other video player works fine, but if I wanted to use them, I would have never installed iTunes in the first place, the idea being that the integration was the blessing.
I USED to be able to watch a video, use Photoshop CS2, have Flash 8 open behind it, After Effects running on a seperate monitor, browse the web, and play freecell all at the same time, with several background utility style apps going all at the same time with out a hickup.
After trying the IDE fix's, the sound setup fix's and any other fix's found in the discussions (and yes, reverting them after they failed to fix the problem), I'm still having an issue, and now I can't find iTunes 6 to try to get back to a good time in life... oh why oh why apple, why do you have just as many issues as windows? I had hoped for so much more....
Anyone? Any Ideas? Anyone willing to email me itunes 6 so I can get back to a better time in life? Or provide answers? I've got a horriable track record with apple (over 20 business stopping questions, and to date 0 responses) so I am about 2 minutes from giving up
Sorry apple, but this is way past frustrating... were all your win/tel beta testers using mac's?
HomeBuilt Windows XP Pro ATI 9700 Pro / AMD Athlon 64 3800+ / hampster on treadmill running his head off...

Are sure that's not Flash needed for those videos?

How can i monitor network traffic to debug video playback issues from a NAS?

I am having problems playing videos on my new Mini that i am using as an HTPC.
I have a brand new Mac Mini running Lion with a 2.7 i7 processor and 8GB of RAM with a wired connection to a switch. .
My switch is a NETGEAR ProSafe GS108T-200NAS set to default settings. I haven't had a chance to start messing with VLAN settings or anything else. There is a bit of a learning curve on my part on this end.
My NAS is a ReadyNAS Pro (RNDP6000) with 3 x 1 TB hitachi ultrastar (HUA722010CLA330) drives and a 1.5 TB seagate (ST31500341AS) drive setup in RAID config using X-RAID2.
The problem I am having is video playback when accessing large video files off of the NAS. These are typically 1080 HD mkv files.
I have tested movies as small as 7.5GB with only slight stutters on occasion. I tried a 10.5GB movie and the stalling was much more pronounced. Movies larger than 11GB are completely unwatchable stalling every minute or so.
I have also tried large movies on the local drive and that is not a problem at all - they play back just fine. Beautiful playback in hidef. Mind you, some of these are the same files that were stalling over the network.
I have also noticed that some other network devices get kicked off the network when a movie is playing.
I think it has something to do with the transfer speed of files over the network and the switch - i am no expert at this mind you.
I am wondering if there is some sort of utility that i can use to monitor network activity on the mini so that i can fix my problem. Or has anyone made chages in their switch settings to optimize data trasfer speeds.
Any advice or recommendations on.
Thank you all!

OK, I did a couple of things and ran things a couple of times.
First what I did settings wise:
I enabled jumbo frames on the Mac Mini, ReadyNAS Pro, and the Netgear GS108T switch. All with MTU set to 9000.
I went ahead and enabled jumbo frames on the rest of the computers on the network just in case.
After these changes I ran into the same problems with videos timing out - very annoying and frustrating as you can imagine.
Then I started playing with device configurations. My original configuration was NAS > Netgear switch > Mac Mini. I went ahead and switched the switch to an Airport Extreme I have as my WAP and the setup looked like this - NAS > Airport Extreme > Mac Mini.
Well, long story short, no go. It appears to me that the NAS is the one having issues providing the necessary data at the proper speed. I also tried playing sopme movies off of the NAS onto a desktop i have and had the same issues - choppy frames and crashing movies. I even tried connecting wirelessly to see if that would work.
BTW, I have the Mac accessing the file system using CIFS.
I don't know what else I could do.
I am going to have to go to the Netgear forums to see if i can figure this out. Hopefully, I can get things going to be able to help some people out.
If anyone has any ideas, they would be greatly appreciated.
My only other alternative is spending $2000 for the thunderbolt capable NAS that Apple sells - it's only money!

Apple TV 2 choppy video playback when mirroring from Macbook Pro (Yosemite) and Macbook Air (Yosemite) but not iOS devices

Video playback is choppy (cuts out every 30-45 seconds) when air playing from both my MacBook Air 1.3 GHz Intel Core i5 running Yosemite and my husbands new MacBook Pro, but runs perfectly when mirroring from any of our iOS devices (iPhone 6+, iPad mini 3, etc.) We have Apple TV 2. This problem just started a few weeks ago, was working fine around Christmas. The problem seems to have coincidentally started right after our son tried plugging in and setting up his Chromecast on our tv. I disconnected the Chromecast, but we still have the problem. All of our software if up to date and I've tried disconnecting blue tooth, we do not have a microwave and our wifi network has a very strong signal. We have an Airport Extreme base station. Is there a solution to our problem?

Hi leahmturner,
I see that you are experiencing an issue with choppiness while AirPlay Mirroring from your computers to your Apple TV. I have an article that contains some helpful troubleshooting steps for you regarding this issue:
About AirPlay Mirroring in OS X - Apple Support
http://support.apple.com/en-us/HT201343
Optimizing image quality
Resolution matching modes
You can choose between two desktop resolution matching modes that let you select which display will have the best image. When AirPlay Mirroring is turned on, select an option under "Match Desktop Size To:" in the AirPlay Mirroring menu extra.
Match Desktop Size To: Apple TV
AirPlay Mirroring changes the desktop resolution to best match your Apple TV, resulting in a 16:9 image that fills the HDTV screen. This setting often produces the sharpest image on the HDTV. The aspect ratio and/or resolution of the built-in Mac display may change to accommodate the Apple TV.
Match Desktop Size To: This Mac
AirPlay Mirroring scales the contents of the desktop to fit on the Apple TV, leaving the resolution of your Mac's display unchanged. Use this setting for the sharpest image on your Mac's display. Depending on your Mac model, the resulting image may not fill the HDTV screen.
Troubleshooting AirPlay Mirroring
If you don't see mirroring options
If your Mac and Apple TV are on the same network, but no AirPlay Mirroring menu appears, your Apple TV may be asleep. Simply press a button on your Apple TV remote to wake it up. After a few seconds, the AirPlay Mirroring menu extra appears. If you still don't see the options you expect, make sure your Apple TV has the current software update installed. Also make sure that you have the "Show mirroring options in the menu bar when available" option selected in the Displays pane of System Preferences.
If the menu bar or Dock is cropped
Some HDTVs have bezels that cover a small percentage of the screen. This can result in a slight cropping of a full-resolution HDTV image. Depending on the HDTV model, AirPlay Mirroring may automatically adjust the picture size to prevent cropping. If you are using OS X Mountain Lion or later, and you see cropping of the menu bar or Dock when using AirPlay Mirroring, toggle the Overscan correction option in Displays preferences.
Minimize video post-processing
HDTVs often apply picture quality enhancements intended to improve the look of film and video sources. In some cases, these enhancements can lead to over-sharpening artifacts when displaying your Mac desktop. Some HDTV models have built-in settings to change or disable the enhancements for use with a computer (computer, presentation, or game modes). Otherwise, the controls for sharpness, detail enhancement and noise reduction can be used to optimize the appearance of the Mac desktop. Consult your HDTV’s manual for guidance on the appropriate settings for use with a computer.
Firewall security settings
If you use a firewall, make sure the following firewall security options have been set to allow AirPlay Mirroring to work:
Choose System Preferences from the Apple menu ().
Click Security & Privacy, then click Firewall.
Click the lock icon to unlock it if it's locked, then type an administrator name and password.
Click Firewall Options.
Deselect (uncheck) the “Block all incoming connections” checkbox.
Select (check) the “Automatically allow signed software to receive incoming connections” checkbox.
Thanks for coming to the Apple Support Communities!

Video playback from Final Cut Pro studders over HDMI

I have a problem playing back video from FCP. The video output will studder during horizontal pans when I output via HDMI. The audio output is not affected.
I have been playing video successfully using FireWire for output in FCP, however, my new video switcher system will not support FireWire output.
What are some possible causes of this problem?
System stats:
* Mac Mini (2010 model)
* 8GB RAM
* OS X 10.6.4 (Snow Leopard)
* Final Cut Pro 7.0.3 (Final Cut Studio 3)

@ Studio X : The files were originally created with Final Cut Pro, rendered out to QuickTime, then are being played back with Final Cut Pro. The file that has the most noticable studdering is a 60-minute timeline sequence in Final Cut. All files are being stored and played back from the Mac Mini's internal hard drive. Everything was originally shot on DV and formatted for a 4:3 aspect ratio.
@ Shane Ross : Are there any settings in the MacOS or FCP where I can improve the HDMI video signal? Or do you know of / have any experience with Firewire to HDMI converters? Unfortunately, my new signal path relies on HDMI from the video playback.
My current setup uses the Firewire output, which is then converted to composite video & analog audio using a pair of ageing DV tape decks. That setup is becoming troublesome due to age.

I just moved my itunes library from a win 7 computer to a win 8.1 computer. Getting an error message "iTunes has detected a problem with your audio configuration. Audio/Video playback may not operate properly. Can't play CDs or get audio file from web!

Help! I just moved my itunes library from a Win 7 computer to a new Win 8.1 computer following the instructions on the itunes website. Everything is good except I'm getting an error message on the Win 8 computer if I try to play a CD or get an audio file off of the internet. I get an error message that says "iTunes has detected a problem with your audio configuration. Audio/Video playback may not operate properly. I don't know where to look for or fix the audio configuration on the win 8 computer. As far as I can tell the iTunes configuration looks the same as on the other computers in the house. At this point I don't dare plug my ipod touch into the Win 8 computer for fear it will get messed up.

I have the same problem and I know that it is due to my PCI Audio driver not being compatible with WIndows 8.1.
iTunes isn't the only program that can't direct sound to the built-in speakers anymore. The obvious solution would be to update the drivers, but unfortunately Dell does not provide an updated driver for my model, so I am stuck with that.
However, saying that, only my laptop speakers are affected by this. I can use sound fine on applications where I can choose the output device and direct sound to the head phones, but for some reason iTunes does not let you choose the audio device manually.
To listen to music I imported the iTunes Library in Windows Media Player and changed the audio output using the following instructions: http://windows.microsoft.com/en-us/windows7/c00d11ba
However, I would also like to rent movie's from iTunes,
Would be great if iTunes would let you choose the output device, too, like most other applications using sound from Skype to Windows Media Player,...
