My Quicktime Player is suddenly not playing videos properly

For over the past week, when I try to play a video the sound is absolutely fine, but the screen just shows green/black fuzzyness. This happened suddenly, i haven't installed or desinstalled anything recently, i haven't made any changes...I don't know what could be causing the problem.

I've desinstalled and reinstalled Quicktime twice- still no luck.

Could it be a virus? I'm using Norton Internet Security and it hasn't found anything either.

Could it be an incompatibility with iTunes? I do download iTunes updates regularly.

Thank you in advance

I am having the same problem with quicktime 7 not playing. The audion is perfect, however the video is scrabled line of green, pink and blue.
I am playing a movie that is .mp4. The format is H.264 decoder, 320 x240, millions AAC, Stereo LR, 48.00 kHz.

The movie plays fine on my Ipod. Any help would greatly appreciated.

Doll,
I just figured out the problem on mine. Do the following,

Open Quicktime 7
Click on Edit tab and go to preference,
then click on Quicktime Preference.
One that opens click on Advanced tab
You will see a selection for video or direct X.
Click on Safe mode (GDI only)
Then click on Apply, then OK.
Restart Quicktime and play a movie to test.

Hope this helps.

Thanks for your advice! It was really helpful. I also went through installation and desintallation. I still don't know what caused the change in the settings. Do you know?

I do not have a clue. Very strange.
Now that I have it working, I started to convert some of my DVD's to the Ipod with software. The issue I am having now is that on playback on the Ipod is not fluid, the movie looks good but has jitters. It seem like it is not running at 30 frames a second.

Thanks so much, your solution worked great!- I was pulling my hair out of my head trying to figure out why my player was dividing every movie into several segments. The same video would play all right in Windows Media player but not QuickTime. The audio was fine however like everyone else were saying. Thanks again for the solution.

Mine did exactly the same, it only happened after I installed Windows XP service pack 2. It looks like it's got something to do with SP2 installation.

SP2 installation? This can cause problems. When I took the a update for XP pro. There was a video card driver being offered, which I took. The driver was wrong for this computer, you must read what microsoft is giving for updates and if the computer can take it. You may think it is just a update to XP OS, but there are so many home or self built computers that the updated software may not comply with various hardware configurations.

Hi Msulli
The same thing happened to me - very frustrating. I found that going to the flash website, following the steps to uninstall the flash player then reinstall it worked. Hopefully problem solved!

I don't know if this is going to be of any help (even though the problem is now solved, thanks to the change made in the Pref tab to select GDI only mentioned in this thread), but in my case what caused Quicktime to misbehave was the update of the Nvidia drivers from version 9x.xx to version 15x.xx - I've tried it a few times now and this happens every single time.
I contacted Nvidia on this but they're yet to post a reply.
When I reverted to the previous version, Quicktime resumed it's normal functioning.
Hope this helps.

I am having a simliar problem, but on my mac and in iMovie will not play correctly - audio is great - video is jittery. It was fine until I updated Quicktime. Any suggestions. I tried to uninstall and go back to 7.1.5 but it won't let me. Any suggestions are appreciated.

I tried looking for the setting suggested below, but they are not under my quicktime preference.

thanks.

Frankly quicktime 7 vs newest is making all movie work and viewing a nightmare. I have installed and reinstalled QT 4 times and the codecs etc which I have spent a lot of $$ on. Still having problems with FLV and more. IF ANYONE has any idea what to do or what not to do please PLEASE advise. I am using QT Pro the latest version and by the way - all was 10000000 percent until this *T&^ version appeared.

Thanks!
