I'm getting very jerky playback on my Vista PC. This is odd because I was having exactly the same problem on my XP laptop. I will do some more investigating (format/codec etc) and give more info. The disc access light goes crazy when I'm getting the jerky playback. What should I try? Is there a program that will list all the attributes of avi/mpg/wmv files? TIA Tony
