My Quicktime Player is suddenly not playing videos properly

Happened after upgrade to QT 7.1.6. Can not play Movie trailers on Apple site using Safari. BUT, if I use FIREFOX, go to the Apple site, I CAN view the trailers. What does that say for tech support?

Called tech support twice last week. Never got a straight answer from the first tech. Second tech was disconnected during a storm and NEVER called me back. There is something wrong between QT 7.1.6 and the Power PC.

Home made QT movies will NOT play on QT 7.1.6, either. Every time, the VIDEO locks up, while the AUDIO continues. Where are the famous Apple PATCHES we've come to know? Is Steve to busy harping the iPhone to worry about QT?

I'm ticked off, because this is something I'd expect from WINDOWS!!!

Have completely given up on Quicktime 7.1.6 (clips, trailers, etc. always freeze with audio playing to end) and am considering giving up on Apple since tech support has been no help whatsoever. The only advice they gave me was to wait for next version of Quicktime to come out and hope that solves problem. I'm still waiting.

I followed Starry Night's advice, but unfortunately, there was no changes for me.
The videos still hiccups a few frames at a time.

Bob:

Thank you for suggesting this fix. It worked for me, too. Before I was able to hear the audio but could not see the video when I tried to play a particular .mov video clip. Instead, when I tried to play this Quick Time video (the video's file thumbnail had a Quick Time Q icon) on my Windows XP computer, I was getting a heavily colorized version of one frame of the video. The frame would change to a couple of other frames as I moved the mouse pointer around the screen.

After I did what you suggested in your fix everything worked properly. The strange thing is that I was able to play the video on Windows Media Player, even though a message warned me that the .mov file type is not supported.

Now what I need to do is find a (free) program that will compress the .mov video so that my son can post it in his You Tube account. As it is now, the file is way too big. Windows Movie Player does not support the .mov file type so I cannot use that program, which I have, to compress the video.

This worked for me (on Windows IE), and I will do my best to remember exactly what I did without proper "Windows lingo" because I'm not a Windows user, but those who are may know exactly what I mean:

In Internet Options, there is a tab (called Applications?) that allows you to select the other (third party?) plugins and programs for your IE Internet functionality. There, in that list, Quicktime was listed TWICE—both ENABLED. I disabled one (hopefully the older one) and restarted the computer, and then everything worked properly.

Hope you all have as much success as I did.

It was my new Nvidia drivers and the upgrade to Quicktime 7.1.6. I used an older Nvidia driver and the problem went away.

I ran into problems with a Nvidia video card, the computer would run fine with the driver that came on a CD with the card but would not work with updates from the Nvidia website for the card. And as I posted a driver for the other card from microsoft XP pro sp2 update created problems, where I had to roll back to the original driver. So my thing on drivers, for now is, if it ain't broke don't try and fix it. But everyone online is always saying update the video driver, with all the self built computers, it seems difficult without knowing the exact hardware configuration. My guess is that it is tough for Apple QT to write software to comply with all the windows configurations, but I may be wrong.

I recently accepted the software update to the QuickTime 7.2 version. Since then any videos start with the "Q" and then play only audio but no video. I don't even have fuzziness, my video screen is completely blank.

I am fairly new to Macs so is it possible to uninstall the 7.2 version and reinstall the older version? Do the Macs have an "add/remove software" function like the PCs? All videos played just find on the older version.

Any help would be appreciated. Thanks, Scott

I've just updated my QuickTime to 7.2 and now I get audio but no video. I'm running a G4 w/10.4.10 and Safari.

Anyone run into this problem before?

I also just let the auto upgrade to 7.2. I can now only play audio, No Video at all. Nice upgrade. I expect this kind of headache from Microsoft, not Apple.

Anybody heard anything from Apple as to how to fix this?

Ditto for me! What's up and how do we fix it?

Same here...
Every single QT web plugin just gives me the the "Q" with a "?" in the middle on 7.2.
