I use PP CS3. Mac Pro Intel. After 2 plus years of working great, all of the sudden, my video will not play in the timeline or preview windows. I can see the video frame I am on, by no play.
I went to preferences, media, and hit the clean button. I checked the previews and cleared those. Also, .movs play fine in QT player, and the clips play in FCP. (I have the Express version, don't care for it) so I think that eliminated hard drive or other hardware issues.
I reinstalled and get the same results.
Help please. Scott
