One of my guys is having Quicktime issues on his machine. Doesn't matter if it's playing in the browser with the plugin or with the standalone player. The audio plays just fine. But the video is mostly just black, and it will show random pixels (I guess that's the best way to describe it) so you can somewhat make out what's going on the video, but not really.

I've completely uninstalled Quicktime and reinstalled, tried the latest version as well as older versions. Get the same result. It's not specific to any one particular video. Does it with any mov file he has saved (which I can view just fine on my machine) or if you go to apple.com and try to watch trailers.

Windows Media Player is showing videos just fine, he can watch stuff on youtube and goodle video. It's only Quicktime that has the issue.

Comp is running Windows XP, AMD64 2ghz processor, and a gig of ram. Nvidia 6200 video card.

Anybody have any ideas?

May I recommend QuickTime Alternative?

I had a problem with non-playing video recently, and the latest version of QTA (v2.0, as I recall) fixed it.

Yeah, I know about Quicktime Alternative... that's what I use at home. I wanted to find out what the main cause of this issue was though.

Seems it not just Quicktime as we thought, afterall. If he puts a DVD in and tries to play it with either PowerDVD or Windows Media Player, audio comes through, but Video is completely black. So no pixelated effect like the mov files, but problems none the less. Codec issue maybe?

Update: I had him install Klite Codec Pack, Quicktime is still jacked up, but DVD playback is now completely broken. Just throws an error saying it cannot playback, don't even get the audio anymore. The error specifically says that the video settings are too high and to change resolution/color depth. It's a widescreen monitor so he's running 1440 x 900 and 32 bit depth. Dropped it all the way to 800 x 600 and 16 bit depth and still gives the same error.

It sounds, not like a missing CoDec, but a bad one that was overlayed, or video drivers.

Have you tried G-Spot?

Update the Nvidia drivers.

Oddly enough, updating drivers fixed the Quicktime issues. I had just put the vid card in and updated drivers about 2 months ago. But there was a new Nvidia update dated Nov. 6th.

Reinstalled PowerDVD and DVD playback was corrected as well.
