I suppose that's possible, but I don't have a problem with any other programs accessing the dvd drive and all dvd's playback fine from the discs, plus it just seems far too repeatable to be caused by dirt.

the duration in virtual dub is correct and it plays back at normal speed, but some frames do appear interlaced (which shouldn't ever happen with PAL) I believe the missing frames are being filled in with an interlacing of the proceeding and following frame.

Thank you all for your thoughts, I will try cleaning my drive but I don't have much hope that it will help, any further suggestions are more than welcome.
