Under Snow Leopard, Quicktime 10 (and 7) stutter on frame-by-frame playback

After I upgraded to Snow Leopard I found that Quicktime 10 stuttered very badly in frame-by-frame playback of .mp4 or .mov files. I use this feature very frequently to study dance videos. I pause the video with the space bar, then move forward or backward frame-by-frame using the cursor keys.
After the upgrade I went back to my Leopard back-up disk and grabbed Quicktime 7 and installed it on my laptop. Quicktime 7 has much less stutter in the playback, but it is still not as good as it was under 10.5.
This is on a January 2009 Macbook Pro with a 2.4 GHz Intel Core 2 Duo and 4 GB of RAM.
I tried changing the settings in Energy Saver to Higher Performance but that did not make any difference.
A friend of mine just bought one of the new 27-inch iMacs and I checked this issue on his computer - frame-by-frame playback is smooth.
Any suggestions or comments appreciated.
thanks
Paul

I had this problem on my old mac mini and then my new mini worked fine. I upgraded to snow leopard and this QT 10 choppy video is BACK! Get this fixed apple! Funny but, if you right click and "open with" the application grapher, it will play the choppy video smoothly/completely normal.
why can't this be resolved??? WHY WHY WHY!!!!!

Remove QuickTime 7 under Snow Leopard

Hello!
I am experience some problems with QuickTime 7 under Snow Leopard in cooperation with Perian and DownloadHelper (a FireFox add-on).
Every time or better said sometimes I use DownloadHelper with Firefox under Snow Leopard on my MBP a process called "QtKitServer" crashes and I get a black screen.
And yes, I installed QuickTime 7 on this machine. I also tested this on my iMac (QT X only!) there this doesn't happen.
This must be a bug in OS X. But I need this tool on MBP without getting any black screens just because of QtKitServer crashes.
So, I found a solution: I want to get rid of QuickTime 7.
But how can I remove QuickTime 7 under Snow Leopard?
Can someone help me?
Thanks a lot!

Hello folks!
I found a work around. A few minutes ago I deactivated the icon preview for "Desktop". And until now everything seems to work.
It seems to be that in this moment when DownloadHelper and Firefox are writing a file on the desktop who isn't downloaded completly QuickLook wants to access that file, can't understand it, and crashes.
So it must be a Mac OS X / QuickTime bug.

I have a big problem with Lion and PGP. After upgrading from snow leopard to lion I cannot access my PGP drive which was generated under snow leopard. PGP does not start but gives a notion that lion cannot work with my PGP version. Solution?

After upgrading from Snow Leopard to Lion I cannot access a PGP drive which was generated under snow leopard. PGP does not start. When I try to start I just receive a message that Lion cannot work with PGP. How can I now access important and confifential informatio which I have stored in PGP (snow leopard). Do I have to move back to snow leopard. If so, how can I do this?

If you have this product,

you have to go back to Snow Leopard.
To re-install SL, back up your home directory, format and re-install.

Adobe CS3 and CS4 updater under Snow Leopard issues

Hey everyone -Ive been trying to research this and I have CS4 and CS3 (just photoshop installed) under snow leopard -(clean install) and when I launch the adobe updater on CS3 it just crashes-and on CS4 the updater runs but finds no updates and I know they are out there.
This is all I could find on Adobes Forumns
http://forums.adobe.com/message/2349031#2349031
They talk about changing the permissions of the admin group but you have to be careful or you will mess your machine up -I dont wanna do that.
Is anyone having this problem? Or can anyone help

You might try creating another user account (testUser) and seeing if those installers will function properly there, under a clean account...

Under Snow Leopard I used a WD My World NAS to back up my Mac Pro (Mid 2010). When I upgraded to Lion I am unable to access the backup because the NAS does not yet support AFP. I have now bought a Time Capsule and want to transfer the old backup onto it.

How can I recover the NAS back up to put on my new Time Machine.
Talking to Apple Support Adviser was a waste of time on case number 239647273
Any thoughts or pointers?

Keep the old OS around and just kick the tires and test new OS. Apple has a history and habit of breaking support in things like this.
You can use TimeMachine as one level of backup, and even there there were changes with Lion, I would always recommend foremost backup clones of every volume. And clone (SuperDuper etc) can be stored on something like HP NAS Media Server which also was supporting TimeMachine, iTunes - until Apple made that harder and more their own proprietary format.

Cloning as a Backup Strategy
Rather than "upgrade" I would clone the system, and do a clean install, then allow Setup Assistant to import your files.

Monitor Calibration under Snow Leopard 10.6.6

Hello,
I´m using a EIZO CE 240 W hardware-calibrated monitor for Photoshop and a second one connected with it for the tools, which worked perfectly under Tiger, but doesn´t work properly under Snow Leopard. Does anybody know this problem? When I disconnect the second monitor it works, apparently Snow Leopard doesn´t work with two monitor profiles. The color is too yellow-greenish.
Please help! Best wishes,
Peter

Recently upgraded from OS X 10.5 to Snow Leopard (10.6.8) and am finding that both Quicktime Pro 7 and QT Player X save movies EXTREMELY slowly - like a factor of ten slower than before. Can't find anything about this, but it can't be right - it's really unusable.
Are you "saving" or "exporting/sharing" the content? (I.e., what are the containers, audio and video compression formats, and dimensions of both your source and output files?)

Playing movie under Snow Leopard

When I play a movie (.mov) under Snow Leopard from inside iPhoto, it uses Quicktime 7. When I export the same movie from iPhoto and play it in the Finder it uses Quicktime X. As there any way I can make it use Quicktime X from inside iPhoto?

OK, thanks, although not the answer I hoped for. Not a big issue, I just prefer Quicktime X. Probably I will update when iLife 10 (or 11?) comes out.

Backing up an encrypted drive with Time Machine under Snow Leopard

In a nutshell, my question is “Can I back up an encrypted drive using Time Machine under Snow Leopard, and if so, how do I access its data from a previous day?”
I have a 1Tb USB drive connected to my MacBook, which runs Snow Leopard. The drive is formatted as Mac OS Extended (Journaled). This drive is included in the drives that Time Machine backs up. I used Disk Utility to create an encrypted drive on the USB drive (998Gb), also formatted as Mac OS Extended (Journaled). The encrypted drive is not on TimeMachine’s list of excluded files/drives.
When I go into Time Machine, I can see the USB drive and the encrypted drive in the side bar. I can access the files on the encrypted drive as long as I’m looking at how it stands now. But if I move backward in time, the encrypted drive is grayed out and inaccessible. If I click on the USB drive, I get a window that tells me it is 75.9Gb in size, and nothing else is available to me.
When I open the back-up drive in Finder and navigate to Backups.backupdb > macbook name > some date and time, I see my MacBook’s hard drive and the USB drive. The encrypted drive is not shown. When I click on the USB drive, I see an entry for drivename.sparsebundle. When I click on that I’m prompted for the password for the encrypted drive. When I enter it, I get a warning telling me that the disk image could not be opened and that the encrypted drive has no mountable file systems.
Is my encrypted drive really be backed-up and if so, how do I access the backed-up data?

Having received a bunch of views but no replies over the last 5 days, I decided to venture into my local Apple store and ask this same question. The response I got from the geniuses was that you can't get a reliable back-up of an encrypted drive using Time Machine under Snow Leopard. So, my only alternative is to copy the encrypted drive's contents elsewhere, unencrypt the drive, and then copy the contents back. This is what I expected, but not what I wanted to hear.

HP Officejet Pro 8500 Wireless Won't Scan Under Snow Leopard

After installing Snow Leopard, my new HP Officejet Pro Wireless 8500 all-in-one printer won't scan. It delivers the following error message: "No Scan Options - refer to device documentation".
Also, when I attempted to check and adjust scan settings using HP's Scan Destinations program, that program hangs and cannot save any setting changes. Then I have to use "Force Quit" to stop the program from hanging up while saving.
HP's software update reports the printer software is up to date.
It appears there are a ton of printer problems appearing for people after installing Snow Leopard, but I sure would appreciate any help on solutions if someone also has this problem.
Thanks much.

I also just tried connecting my 8500 wireless printer directly via usb and then downloading the HP printer drivers from Apple downloads and reinstalling.
The install hangs nearly forever on the final step, but eventually says the driver install was successful. However, then when connected via usb, I am unable to print. Printing works when you reconnect via the wireless on the 8500.
So connecting via usb and reinstalling HP printer drivers does not solve the issue. And it's puzzling, because the list of supported printers under Snow Leopard lists the Officejet Pro8500 Wireless as supporting both printing and scanning.
Somebody has it wrong.
If this scanning problem continues very long, I may be forced to uninstall Snow Leopard, because my printer is brand new.

HP OfficeJet Pro 8500 Wireless second paper tray under Snow Leopard

He there, I have a strange problem with the second (extra) paper tray from the Office Jet Pro 8500. I have setup the tray and activated the option on the driver page on the computers, but no results. No paper is loaded from the tray and there is an error that no paper is loaded in the machine. The printer is connected via ethernet (and a time machine) and I am running snow leopard on all the machines that are connected to the printer. I have installed the latest drivers from Apple and from HP. I know that the paper tray is working, because when I make a copy on the machine localy and force him to use papertray number 2, then there is no problem.
Does anybody have the same problem?? Thanks

PhotoShop Elements 6 for Mac under Snow Leopard?

Hi. Apple's new operating system for Mac, Snow Leopard is being released tomorrow.
According to the Snow Leopard wiki, Photoshop Elements 6 does not work under Snow Leopard:
http://snowleopard.wikidot.com/
I contacted Adobe to ask if they had any plans to update Photoshop Elements 6 to work with Snow Leopard. The response I got from their support was that Adobe Photoshop Elements was programmed before Snow Leopard and so they weren't responsible if it didn't work.
I am pissed because of course Photoshop Elements was programmed before Snow Leopard. EVERY software program was. Most of my software (and I have a lot of apps) are being updated for Snow Leopard by their developers.
I'm writing this post just to make sure that Photoshop Elements doesn't work under Snow Leopard. It's possible whoever posted that Photoshop Elements didn't work under Snow Leopard could have been having an isolated problem.
So, if anyone tries Photoshop Elements with Snow Leopard, please post here whether or not it works.
Thanks a lot.

No, there are no significant known conflicts with Snow Leopard, so that's not your problem. Have you deleted prefs since the upgrade? Was this an upgrade in place rather than an erase install? If so, go to your username>library>preferences and delete:
com.adobe.Photoshop.Elements.plist
Adobe Photoshop Elements 6 Paths Folder
Adobe Photoshop Elements 6 Settings Folder
Opera preferences
repair permissions and see if it's any better. Do you have any third party content installed in PSE? There may well be conflicts with that, if so.

Canon iP6700D Tray Choices Disappear Under Snow Leopard

I have a Canon iP6700D. In 10.5 and earlier, one could select between the automatic sheet feeder and the cassette through selections under "Quality and Media". Those options seem to have disappeared under 10.6.1 using the September 11th Canon printer driver. Nosing about in Google, others seem to have the same problem with this and other printers under Snow Leopard. I've tried uninstalling the printer and re-installing but it hasn't helped.
Settings made under 10.5 and saved still appear in Snow Leopard, and are still able to access the cassette and the sheet feeder, but I can't find a place to CHANGE that for saved or for new settings.
Can anyone tell me where to find this setting, or where I might find a patch that will fix the problem?

The v10.26 driver for the iP6700D still has the Paper Source menu under Q&M on 10.6. I can only think that something is conflicting with your installation of the driver. I would trash the contents of the BJPrinter folder, located in HD > Library > Printers > Canon. Then install the v10.26 driver again and see if the menus are present.
There were two versions of printer drivers available for 10.5, v5.8.3 and v10.xx. If you had the version 5 installed and had presets based on this driver, then they will not work correctly with the v10 driver on 10.6. You should Delete these presets and create new ones once you get the Q&M menu appearing on your install.
Final note. You should be posting this question on the Snow Leopard forum. This forum is for Leopard printing and scanning issues.

TS2510 problem with soundtrack pro v2.0.2 under snow leopard

Hi, I've just upgraded my mac book to snow leopard and now when I try to record something with soundtrack pro v2.0.2 through the line input jack, the internal microphone is still switched on and none of the preferences allow me to switch to the input jack,ks
Does anyone know whether STP v2.0.2 will run ok under snow leopard? If I need to upgrade the drivers, does anyone know where I can find these and how to instal them.
Many thanks.

There are no "drivers".
Use Audio MIDI Setup to set your audio input.
Good luck.

Font problem with MX under Snow Leopard

Anybody know what might cause an app built with Director MX not to display an installed (not embedded) custom font under Snow Leopard?
The program was built quite some time ago but was tested under previous Mac OS X.x versions and worked fine. What might have changed that could cause this problem?
Complicating this is that I don't have Snow Leopard myself to test it directly, but here's what I do know:
The font is definitely installed and available to other apps.
Everything else about the app works fine.

I noticed the same jumbled text problem.
When I went to look at Font Book, I see that those fonts are no longer installed. It must've happened when I loaded Snow Leopard last weekend.
Anyway, I went to reinstall fonts, and I see I've got a bunch that got uninstalled. But when I try to reinstall them, like Calisto and Caligula to name the first couple I tried, Font Book reports that there were serious errors when trying to load them.
Does anyone have insights into the vague message: "System Validation" as the serious problem? I don't see a way to get more details about the problem than that.

HP AIO: Scan to Computer STILL missing under Snow Leopard?

Has anyone gotten any info on the status of the "Scan to Computer" and "Copy to Computer" (for reading memory card) under Snow Leopard? Being able to scan and copy files from my AIO directly to my Mac under Leopard was freaking awesome. Now I have to acquire images from the Mac (which works) and there is no way to automagically copy over files from the card reader at all.
It's a real bummer to have to use a Windows machine to do these things... Especially since it was working fine in Leopard and we've been waiting months with no work and the only HP person appears to no longer be able to post here.

Uh-huh. I beg to differ and think it is an Apple issue and an Image Capture issue in particular.
I have a nice new Epson SX610FW that is absolutely stunning in Windows Vista.
It also has Epson Scan application that does scan but Image Capture sticks and will not talk to the scanner.
Plus on Windows I can fax from the 'pooter using Epson Fax, in OS 10.5 or 10.6 no fax option is available.
I am of the opinion that print, scan and fax is broke in OS 10.6
So, in my case on a wi-fi capable all-in-one:
Windows Vista Home Premium
Scan
Print
Fax
On the device
Copy
Fax
send scan to a declared network computer (I have not tried this too thoroughly but it looks broke on OS X)
In OS 10.5
Scan
Print
no Fax
or 10.6
Scan with Epson Scan but not with Image Capture or Preview (Preview fires up Image Capture with no option to use Epson Scan instead)
Print
no Fax
Why won't OS X do Fax easily from an all-in-one - a relatively new all-in-one at that?
Interim conclusion
Image Capture is broked in OS 10.6
Fax is strange in OS X
