Hiya I've had some major issues with this in the past:

Whenever I play anything the audio plays but the Video stays on whatever frame its in in the timeline. I can move the video manually so all the video is there. 

I have tried importing and recapturing files to see if it is the files, but still no luck. I have tried important 2 jpegs and putting them on the timeline, but still no luck.

I've just upgraded to windows 7 (64bit) and installed Media composer 3.5

I have a NVIDIA Quadro FX 3500 installed with a 169.47 and Version 7.5.5 of quicktime.

I have tried reinstalling the drivers for these

I have tried the video display settings on both my graphics card and software OpenGL

I have tried turning on and off the legacy overlay feature

This problem has been driving me mad for ages if anyone has any ideas please please help!

thanks

Ali

Ali:

The Windows 7 OS has not yet been certified for use with Avid software. You should be running Windows Vista Business or Ultimate 64, or Windows XP Pro SP 2 32 bit.

...and when you do have this issue, it's because the Video Card Drivers are not compatible. Which would make sense for Win 7.

When i had vista installed i still had this problem - I'm going to rebuild with vista 64 bit, but if teh problem persists, what would you recommend?

1. Check that your Video Card is supported

2. Check that your Video Driver is supported

When I installed Windows 7 64-bit, I had the same problem with Media Composer 3.5.4. Windows auto-update has then proposed a new nvida driver, which i installed, and the problem disappeared. BTW, I am now running the latest W7 driver for Quadro whitout any problem. It is version 191.00 downloaded from nvidia.
