Distorted songs on burned DVD

I created some movies in iMovie using still photos from iPhoto, and added songs from iTunes. Then I burned a DVD using iDVD. Playing this DVD on my Panasonic DVD player and TV, some, not all, of the songs are distorted. Everything sounds just fine on the computer, previewing in iMovie, iDVD. Even playing the offending DVD in the computer doesn't have this problem, only on the TV. Any thoughts?

I was wondering if you ever fixed all the issues as I'm having similar problems. I didn't have this problem when using the iMovie HD and iDVD combo. But now that I use iMovie 08, iDVD 08 and Garageband (forced to use because I want custom chapter markers) I have had the same audio distortion with several projects using various downloaded (amazon) mp3's or LAME rips 224 kbps or higher. I checked the dvd on my PS3 to Pioneer plasma...sounds distorted. Other computers and "simple DVD" players the song is high but can't tell the distortion.
So here's what I'm trying to answer
Is it my PS3-Pioneer TV?
How does the normalization in iMovie work? Does garageband undo it?
Here's why I ask...I set the volume levels for 75% on all music tracks then normalized and exported, loaded in Gband, added chapters and re-exported using share to disk. I saw something speed by that looked liked it said normalizing, and was wondering what that does to the track that is supposedly already normalized.
I plan on running a few tests so that I don't have deal with this again.
I have re-done the audio without normalization, but volume at 75%. I'll import this direct to idvd...test
same thing only run through gband then idvd..test
Any help/info is appreciated...
PS..I usually burn on TDK DVD-R's

Plays ONLY some songs when burning dvd

Can anyone help me out here? I have 4 songs in our play list for the dvd...when we preview they ALL play, when we burn only 2 or 3 play. What is up with this?
Thanks,

Suggest you create a disc image and then burn the DVD. File/Save As Disc Image...
http://docs.info.apple.com/article.html?artnum=164927
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (not the .img, the one below) in the left-hand window. Click the Burn icon. Your SuperDrive tray will open. Insert a recordable DVD. (DVD-R preferred by me.) Click the Close button. Wait. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
b Also, you can use DVD Player to play the virtual disk to check your iDVD 5 project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

Keynote- Second song distorted in burning DVD process

Hello,
I am in need of help... I am trying to turn my keynote project into a burned DVD for a friends' family as they have just lost his mother. I made this project for the funeral (as I have done numerous times before with no problem) but for some reason, whenever I try to format it and burn it in the DVD program on my Mac the second song becomes distorted and I can't seem to get it fixed. I have wasted numerous discs but even when I watch it as a DVD on the Mac it's distorted. The only time it isn't is when I "preview slideshow" in Keynote. Since I couldn't get them burned for everyone after the funeral, I am trying to get it fixed and sent out for Christmas. Any help is GREATLY appreciated!! Thank you.

hi Denise and Spencer!
I looked on history questions for this error code 261 and previous people commented only as it relates to MP3 players stating that the error code was due to having apostophes or dashes. In other words you must have alpha characters. That didn't help me because I had all alpha characters and I still get and error code 261.
yep. i agree. there must be something else going on with this ... prior to the "&" workaround coming to light, i'd also seen people get past this by doing things like firmware upgrades. finding out what other things can help with people might be a bit of a pain, though. (no guarantee that the same thing will work for everyone, too. a firmware upgrade didn't cut the mustard for all people with this.)
if you feel like being guinea pigs, we can steadily work through some possibilities.
probably the first place to start would be a generalised check on drivers and firmware. let's not just look at the CD drives. let's have a look for everything available for any particular machine. video drivers are worth checking up on. your itunes "help > run CD diagnostics" might be a good place to check, too. are those recommending that you check for updates for certain components/drivers?
these resources might be helpful, too:

Hi
No audio on DVD disc.
Most common origin.
1. Imported audio from iTunes.
• In iTunes copy out as an audio-CD .aiff
• Use this in Your movie project
2. Low - Free Space on Start-up/Boot/Internal/Mac OS Hard disk makes it hard for iMovie to work as intended.
Down to 1.3 GB and it doesn’t work - especially audio don’t migrate over to Media Browser
(iM’08 & 09)
3. Material in iMovie’08 & 09 - Shared to Media Browser and here selected as Large
large.m4v. It silenced out this project in iDVD. By making a slight alteration - provocing it to ask for a new Share/Publish to Media Browser and here selecting 640x480 - and audio was back when a new iDVD project was created including this movie.
176x144
480x360
640x480
720x540 960x540
4. Strange audio formats like .mp3, .avi etc.
• Change them to .aiff. Use an audio editor like Audacity (free)
5. Main audio is set to off in System Preferences - Does this by it self - Don’t know why
Cheque Audio-Out resp. Audio-In
6. Ed Hanna
Had the same problem; some Googling around gave me a kludgy, but effective fix
Downgrade Perian from recent versions back to version 1.0.
That worked for me, and so far I haven't encountered any deficiencies—except it takes more advanced versions of Perian to enable QuickTime to handle subtitles in .srt format—that I have noticed.
7. GarageBand fix.
In this set audio to 44.1 kHz (Klaus1 suggestion)
(if this don’t work try 48 kHz - me guessing)
Before burning the DVD.
• Do a DiskImage (File menu and down)
• Double click on the .img file
• Test it with Apple DVD-player
If it’s OK then make Your DVD.
Burn at x1 speed.... (or x4)
• In iDVD 08 - or - 09
• Burn from DiskImage with Apple’s Disk Utilities application
• OR burn with Roxio Toast™ if You got it

Burning songs to a DVD............

Does somebody know how can I burn all songs to a DVD from a specific playlist? I ‘ve done it without success, because it doesn’t let me burn all of them, it jumps from 8 to 8, and I already check all the songs. Weird ahh? HELP PLEASE.
hp pavilon Windows XP

Hi, noisyjon.
Can you select each track as a separate region and use save as to write them as in dividual tracks. Another way is to use the locators ans select how much of the full track [the entire dvd] you want to bounce and save that file.
ie. say track 1 is from bar 0 to bar 71. select that in your bounce menu and logic will only bounce that portion of the project. You can also name it whatever you want in the bounce drop box. Repeat for each track.
Hoe this helps,
Regards,
Scorpii.

Distorted downloads when burned to CD

I purchased some music and then burned it to a CD. This has created cda files. However when i play these (on a different computer) from the CD the songs are all distorted (sort of on fast forward with clicks!!)
Are there some restrictions that I'm not aware of? Any suggestions to fix so I an play the purchased songs from a CD?
Many thanks

I've tried verbatim +r media at 4x and 2.4x both result in garbled audio. I've also tried burning via .img with no luck.
I've also tried imation -r media at 1x 2x and 4x all with the same results as well.
The issue might be related to 8bit sampling instead of 16bit sampling from the source so I tried exporting the iMovie files to quicktime to create the "16bit" this also did not help. Also note that when extracting audio from a clip, and looking at the waveform, the waveform is far from clipping where I get the overdrive audio.
This might be something related to overdriven audio from the source media, which does not distort on the computer, even when playing a burned DVD.
ACK. I've spent over $70 on this project and am coming up empty handed. :/ Thanks Apple. I think I'll consider warez-ing FCP & DVD Studio Pro so I can check and correct my audio levels (just kiddin!)

Music dropping in burned DVD

I hope someone can help. I tried just about everything that everyone has suggested so my DVD will burn properly, but my music keep dropping at the same point in every DVD that I've burned.
This is what I've done so far:
Made slideshow in iPhoto - played beautifully for a Relay For Life event. People want copies.
Shared to iDVD from iPhoto Slideshow. iDVD kept crashing at startup.
Went to Apple Discussions and took someone's advice to reinstall iDVD, in the meantime,
Sent to Quicktime Player (played beautifully). However, can't burn from QTP
Saved as .mov file, but iMovie doesn't import it as video
Reinstalled iDVD
Made DVD from iPhoto album (not slideshow) and iTunes Playlist (previewed and it played beautifully again).
Burned DVD, played it - audio dropped for 2-6 seconds in two of the songs
Went back onto Apple Discussions
Figured out that I should re-format my music to AIFF files which I did.
Edited project with new music
Burned another DVD (Maxell DVD-R)
Again audio dropped at same spot again
Went back onto Apple Dicussions
Took suggestion to saved as image file.
Burned to DVD at 2.4x (my lowest setting) for 5th time and music still drops at the exact spot on each copy I burn.
Right now I have the same project in .dvdproj, .mov and .img
I made a DVD about 18 months ago, when I was new to Mac and it was the easiest thing ever. I never had anything close to this happening, or I would never have attempted it again.
I'm out of ideas - can anyone give me other suggestions.
Thanks!!!

Can you confirm you are using iDVD 7 from iLife 8?
This will not run on Tiger, it requires Leopard.
If you are running iDVD 6 you are in the wrong forum, but we will carry on here!
Previewing in iDVD is not the same as previewing the final version prior to burning.
To preview the final version, without wasting another DVD blank, go to File menu and click on Save as Disk Image.
This creates the final version and does all the rendering etc short of the actual burn.
If you open DVD Player you can play that Disk Image as though it was a DVD.
If everything works, only then burn to a DVD. In this case use Disk Utility to burn the DVD - or better still, invest in Toast.
As for the audio drop-outs, are you sure you are using AIFF files that are not DRM copy protected?

Idvd 09 - preview looks awsome, burned dvd looks like crap on a stick!

What is going on with idvd???
1. I use a Panasonic HD digital camcorder that saves video in 1080p x 720p and looks spectacular veiwed directly from camcorder to TV.
2. I import the video files into imovie 09 and quality still looks great. (I realize my monitor won't display video at it's highest resolution.)
3. I edit the video and as the text and transitions are added the playback gets choppy and starts to freeze. -Whatever!
4. I "share" the final vid to media browser.
5. I create a DVD menu in iDVD 09 and import the video from the media/movies panel.
Preview looks great, runs fairly smooth. ok!
6. I burn to a DVD-R using the Best Performance setting.
7. I place the burned DVD into my dvd player and....
It now looks like I am projecting the video onto a brick wall with the focus out of adjustment. The video is not very smooth, with jittery motion! And the resolution mimics that of an old Sega Game Gear view screen! Text has video noise distortion all around it. Probably would look better on youtube! AND....If I select "Scene selection" option and choose a scene from the middle of the movie, it just plays from the start anyway!
So much for HD! So much for deadlines! Now I just want to know why I "upgraded" to iLife 09 and a new-found crappy quality!! "Hollywood style movies" - MY BUTT!!!!!
Please help!!!!!!

Hi Jerred,
Welcome to apple discussions. I have some bad news and some good news for you. I'll start with the bad news.
iDVD does Not support burning High Def DVD (even though iMovie will in fact edit HD). That's the bad news.
The good news is that there are third party options available to you at a relatively low cost (under $120).
See here: http://www.roxio.com/
OK. I told you the bad news and the good news right? Well here's the frosting on the cake:
You DON'T need a BD burner if you're doing this on the cheap (like most of us). A standard DVD burner such as your Mac's superdrive will do fine.
See here: http://www.macvideo.tv/dvd-authoring/features/index.cfm?articleId=112361
Btw, you do want to make certain your camcorder/ camera is listed below prior to proceeding with the above info:

Only one iTunes song plays during DVD slideshow

I have built a slideshow in iDVD6 that's about fifteen minutes long. I added four purchased iTunes tracks, grouped in a playlist, into the audio well in iDVD. The Project Info shows the four tracks.
Only one track plays, however, on the burned DVDs. It repeats itself several times until the slideshow is finished.
In reading other posts about audio, I've noticed that too little available space on the drive with the project can sometimes make iDVD a bit wonky.
I have about 15 gigs available - could that be causing this problem?

15GB should be sufficient, although more always is better.
On the chance that some preference or permission is corrupted, try the following standard stuff that we do when an iLife program is acting weird: Close iDVD and trash the file com.apple.iDVD.plist found in User/Library/Preferences. Then do a permissions repair using the Disk Utility app on your Mac.
If that doesn't solve it, as a workaround you could try joining the songs in your playlist into one total soundtrack. You could do this by putting your playlist into an iMovie project and then exporting your playlist onto your desk top as an aiff file. (File/Export/Expert Settings/Share/Sound to aiff) Then import that file directly into your iDVD project, or into iTunes and from there into your iDVD project.
Another way is to export your playlist to a musical CD, and then import all the songs at once from the CD back into iTunes, checking the "Join CD tracks" option on the iTunes Advanced menu. That will join all the tracks into one long clip.
Perhaps someone else will come up with a better suggestion. Good luck with this.

For things like burning dvd's, would the jump...

For things like burning dvd's, would the jump from 2GHz to 2.26 GHz on the mini make a noticeable difference?

Use Toast, it makes "Audio DVD's" (which are not the same as the DVD-Audio standard but a huge disk of audio files).
From their help:
Making a Music DVD
A Music DVD can be played in a set-top DVD player or in a Macintosh or a Windows computer with a DVD player. A Music DVD should not be confused with a DVD-Audio disc. DVD-Audio discs require a special DVD player. A Music DVD is a standard DVD that contains music (and can also contain photo slideshows and videos), has full navigation menus for song selection, and can be played in any set-top DVD player.
A standard Music DVD can contain over 50 hours of music with Dolby Digital sound. If your recorder supports dual-layer recordable DVDs, you can create a Music DVD with over 100 hours of music.

No audio in movie portion of my burned DVD

I used Final Cut Express to save a Quicktime movie on my desktop. When I open this movie, it plays perfectly -- meaning the audio is fine.
I transfered the movie into iDVD, where I finished the menus (including audio). The movie plays perfectly in iDVD.
But, when I burn the movie to DVD, it loses the audio in the movie itself while keeping the audio in the menus.
Can you help?

E,
Did you find out the cause of your problem? I'm curious because I experienced the same thing, I think. I'm a newbie, so excuse my explanation...
I imported super8 footage into a DV camera. The mini DV tape played back beautifully. Furthermore, it imported into iMovie beautifully. The completed iMovie, which consists of a menu, an iTunes selection as an intro, a few titles, 5 minutes of video in which there are people speaking, and some stills from iPhoto. It plays perfectly in iMovie. Additionally, the burned DVDs (I made several attempts) also play perfectly--WHEN THEY'RE PLAYED ON A MAC. When I play them on ANY standalone DVD player (cheap or expensive) the audio which is embedded in the video IS SILENT. All other audio, like from the iTunes song and the menu is fine.
Bengt W suggests the following from Jan 14, 2007:
"Two other reasons for missing sound:
- use of iTune downloaded music in the movie. To make this work I would
export out the needed audio to an audio-CD .aiff from iTune and use this in
iMovie
- If You do as I (You write that You didn't) Not using the Share/Export to iDVD
from within iMovie. I close iMovie and open iDVD then import the iMovie
project. This stops iMovie from rendering and lets iDVD do it so much better.
If You intermediat - between closing iMovie and open iDVD rename Your
movie project icon on eg. the desktop (or where You store it) it will result
in a DVD disk without sound on the movie."
Do I understand this correctly? Is he suggesting I/We mistakenly renamed our projects between iMovie and iDVD in the movie's icon on the desktop (or wherever we stored it)?
I opened the movie through iDVD just now, allowed its title to appear in the theme window, and reburned. No luck.
If you have further insight to share, I would appreciate it. I'm sorry to say I don't understand a lot of the jargon, but I'm trying...

LP8 - burning DVD-A?

So, Logic can burn DVD-A - does it support indices to have several songs on one DVD-A (e.g. by using the markers inside the Arrangement)? Or is it just for burning one song to DVD-A?
Thanks
best
Message was edited by: steff3

Hi Steff,
Well, I've burned a DVD-A via Logic - only to discover I cannot play it back... I have no DVD-A player and there appears to be no freeware DVD-A player for OS X around... therefore I could not discover if the markers (about 12) I put in this project have had any effect... maybe you could somehow investigate the files on this screenshot? I could even mail it (the AUDIO_TS folder) to you, so you can 'reburn' them to check if the markers are applied in it. If not, I guess you would have to burn separate sessions of separate songs - quite a hassle.

MacBook Pro 13 inch will not recognize a burned DVD

Bought this computer in August and last night (October 15) I inserted a burned DVD which the Super Drive will not recognize. What's worse, I can't eject the disk. So it's sitting in the drive doing nothing. Any suggestions on ejecting the disk? Anybody want an almost new MacBook Pro 13?

Launch iTunes, make a one song burn list, and tell it to burn a disk. Your Mac should pop out the old one and ask for a new one. Then quit.
Does it recognize any DVDs?
Are you giving it away for free?

I repeatedly get "error during rendering/encoding of menus/slideshow" message. This process is the same on my iMac, MacBook and another iMac. I have been burning dvd's int he same way for the past 12 months using the exact same steps successfully.

I keep getting "error during rendering/encoding of menus/slideshows" message. I have been burning DVD's in exactly the same way for the past 12 months and mostly on my MacBook which is 3 years old. Obviously I'm using iDVD. I purchased an iMac about a year ago and moved to use this for dvd burning without problem. A few months ago (approximately) I started to experience problems with burning with the error message above. I tried everything including starting the whole process from scratch right down to capturing the movie clips from my video recorder into iMovie, then using them in iDVD. Still the same message came up. I lost count of how many times I repeated the process with different clips and variations and the same thing happened. This was also the case with my MacBook and my husband's iMac.
After taking both of mymac's tothe service centre, having new optical thingys put it and even a new hard drive on my iMac along with a new DVD burner the same thing happened. They told me it must be the process that I am using that is incorrect!
I took my 27" iMac to an apple shop and asked them to assist me while I use the same technique as I always had. The same message came up so they tried using my clips in one of their mac's. The same message. They tried it with different clips and the same message. The only way we could get theirs to work was with a magic DVD which did not produce what I needed and was limited with only one page.
I now cannot use any of my Mac's for the intended purpose that I bought them for - to produce good media for my work! It was suggested that I purchase some non Mac software to burn DVDs which defeats the object of having a mac with iDVD in my opinion. I have a book on iDVD which is very informative and have followed the process to the letter and checked all the trouble shooting and still no remedy. It was mentioned that an up-date may have caused the problem on all my macs.
I feel that this issue should be addressed by Apple as a matter of correctness.
I now find that on the net there are many posts in forums and such like with exactly the same (almost word for word) problems. Please Apple, keep/regain your good name and sort this out.
Jayne Connelly

Thanks Bengt W for your attention to this matter. So much appreciated. And thanks for putting me right on the aim of forums (new to this). Although, you may regret asking for more information. I've added everything I can below.
The process I used is as follows:
Import recorded clips of between 5 and 15minutes each from my video recorder into i
Edit the clips (remove unwanted start and endng)
Add title to front of clips
‘Share’ them to ‘movie’ (export using QuickTime)folder in .mov format individually
Open iDVD and ‘create new project’
Select ‘favourite’ theme that I have set up forall my work dvd’s (this has been used successfully many times and I’ve triedwithout using the favourite them).
Add 2 submenus for each group of clips
Select submenu - drag and drop between 3 – 6 clips in each of the twosubmenus
Change title colours on clips
Dragand drop image into drop zones where required
In‘map’ view I check for any yellow warnings before burning to disc
In an attempt to remedy the problems I’ve tried the following:
Try new DVD discs
Try different themes (favourites and standardones)
Change images in drop zones
Start whole process again even from importingfrom camera again
Two other completely different computers (iMacand MacBook) with iDVD
Go to apple shop and use their computers to doin iDVD
Try with one clip and no menu pages added
Use a clip that I already have that did notoriginate from my camera
Turn computer off and restart
New hard drive
New optical lense (thing)
New DVD burner
Saving to disc image rather than dvd disc
Other points:
I also have a ‘flip’ and ‘iPhone’ whereI’ve imported footage camera which, although limited, records and makes videoclips and burns them to DVD through iDVD without problem.
For example, I have just gone through steps 5 - 11 using some clips that were already imported from my iphone to iPhoto and dragged across. I used a theme that I've used before which has failed and added one sub menu page where the clip went. It burned to disc image successfully.
The startup disc, I believe will have no space issues asit’s a new hard drive with no use apart from this. That could have been an issue before (I didn’t check it) butnot now.

Can't burn DVDs? Try this first...

Like a number of other folks, I had an unexplained failure to burn DVDs and thought something Very Bad had happened to my drive. However, doing some research before buying a new drive (if I had to buy one, might as well get the Latest and Greatest right?) I found there's a lot of really bad media out there. Companies are buying some really cheap junk, slapping their label on it, and putting it on the shelves.
So before doing anything drastic, try this:
Go to Applications -> Utilities and start "System Profiler".
In System Profiler, left hand column (labeled "contents") click "Disc Burning".
Insert a disk you haven't been able to burn.
When (sometimes "if") the disc mounts, refresh System Profiler (command-R or from the View menu select "Refresh"). At some point, you should get something like this:
Media:
Type: DVD-R
ID: CMC MAG. AM3
Blank: No
Erasable: No
Overwritable: No
Appendable: No
Pay attention to the ID field. In this case, "CMC MAG. AM3"
Pop over to:
http://www.digitalfaq.com/media/dvdmedia.htm
And search for your disc ID. This likely is "all run together". That is, for "CMC MAG. AM3", you look for:
CMCMAGAM3
And, presto, the discs my drive "quit" on are listed in the section:
"4TH CLASS MEDIA:
"Pathetic garbage media, landfill material, about 0-50% success rate. These discs are pretty much only suited for preventing drink cup rings from forming on a table. Most of the time, these are ready-made coasters. If you can actually get a burner to acknowledge the disc, do not expect much. And if the burn actually succeeds, do not be surprised if a DVD-ROM or player chokes on the disc (read/play errors). Cheap prices, cheap junk quality."
How nice!
Mind you, I did not buy "CMC Magnetics" discs. I bought a "brand name". I got CMC Magnetics discs with a "brand name" label. And, apparently, their lowest quality (they do have some listed as "3rd Class Media" but not the ones I have).
This would also explain why I managed to get several burns from the spindle then everything just up and stopped. A "0-50% success rate" means I can expect half *or more* of the discs to fail. I managed about 30% before reaching a run of total garbage in the spindle.
(In fact, many of the remaining discs--I've taken different ones out of the spindle at random--won't even mount.)
Also, the fact that companies are "out sourcing" means that even though you may have tried different "brands", you may actually still be getting discs from the same crappy factory! Scroll down to "Branding Guide" at the digitalfaq.com site and you find that CMC is supplying (among many):
Datawrite, HP, Maxell, Memorex, Staples, and some TDK even!
Buying different "brands" doesn't necessarily mean you've bought different discs.
So before doing anything drastic, before assuming the drive has konked out, buy some one packs or three packs of the "1st Class Media" and try them. I haven't a problem with the ones I bought from companies listed as providing "1st Class Media".
Based on the "Branding Guide", I suggest buying a few from one or more of:
Verbatim
Sony
Panasonic
Then see if your drive problem suddenly clears up. Did for me. Now to figure out what to do with the 60+ CMC coasters I have left...
