I'm asking any1 to pls help me by telling me an alternative TO quicktime & vlc in Vista...I tried vlc but there was a choppy audio in contrast to no video by others and quicktime did not play with an error message in my 32 bit Vista"QUICK TIME PLAYER requires Windows 2000 or later. Please make sure that the compatibility mode is disabled in the compatibility tab of the properties for quicktime player.exe” . Iam using EMC 9 but i cannot include movies/videos (.mov files) without an alternative media player...any suggestions?

I'm surprised of the problems in VLC. It's been perfect for me on many machines with different OS's. Have you checked to make sure you have the latest audio and video drivers?
Winamp is another great media player.

Are you using the latest version of Quicktime -- it lists Vista compatibility on the Q/Time site, & haven't had any problems myself.

For other players visit videohelp.com -- they have an extensive collection of downloads and links to different media players including something called Quicktime Alternative.

Are the video files you're trying to work with somehow damaged or bad? Have you or someone else been able to play or work with them, maybe on another PC?

In order to play &/or work with video your PC needs codecs installed that can work with that type of video compression or encoding... Quicktime is similar to the Windows avi format in being a container for video that's been encoded using 1 of several possible formats. Could this be the source of your problems? If you don't have the needed codec installed, or Windows is trying to use the wrong codec, or you have a conflict between different codecs, these can all cause problems -- the last 2 are more common if you've installed a "codec pack".

If you can't get it working it might be worth the time/effort to check out the forums & guides at videohelp.com to see just what is required for the exact type of video you're working with.

Will audio plug ins help?

While they won't hurt, I don't think it will help in your situation.
Just remembered another neat and small player----media player classic
