Recently, clips over 2 minutes in length have been inconsistent: audio, but the video freezes and the timecode does not advance, or, plays, pauses, picks up and stalls again. I have been using CS3 Production Premium for over one year without incident. I have tried deleting and re-capturing these clips with inconsistent results. The clips behave similiarly in Windows Media Player as they do in Premiere. Premeire is taking several minutes to generate peak files and these clips are difficult to copy to other machines. Is this a potential PC virus, an Adobe issue or a Windows issue?
