problem with preview

[Digital FX]

Recently I noticed the preview in finder window were not reading any of mp4's that downloaded of youtube. All I can say is this (1) Any mp4 videos that were copied from dvd using a program called handbrake work fine. (2) Any flv videos work fine and (3) any flv's that were converted into mp4's using isquint I only get sound and not the video.

This no big deal or anything but I would like to know has anyone had problem and do that know how fix it.

All video play in a Mac program is handled by QuickTime plugins. So have you installed the QuickTime plugins Perian and for Windows Media Flip4Mac player yet?
