Sir Adywan! An honor to speak with you again, hombre. :)

Are you burning it to DVD or watching the extracted VOB files on the PC?

The latter.

Haven't heard anyone having any problems with the purist. Do you get an ISO file when you unpack? If so then try mounting the image with Virtual clone drive, daemontools or something similar and try playing the movie from that. if it plays smoothly then PowerISO is causing the problem.

Aye, I get an ISO. When I play the movie directly from the ISO via both clone drive and daemontools, it works beautifully. When I access those same files in the same way through Womble, however, the stutters/glitches appear. I tried copying the VOB files out of the ISO file onto the regular hard drive; the Womble problems recur, in fact, once the VOBs are copied to the hard drive, all my video playing/reading programs experience minor glitching. I try pcgdemuxing the IFO from the IFO and loading that into Womble - problems again. Aaand, I at long last pop the regular Revisited into Womble: same story, and in the same spots.

I can't imagine why PowerDVD should read the ISO file perfectly but Womble won't, but if I can't manage to get this working in the latter it won't be the end of the world. At least I'll always be able to read the original ISOs via clone drive. :)
