Thanks for all the info. folks. My question was purely out of curiosity, as I did not have a multi-episode DVD to play around with. I now have one and have found that Smartripper and Decrypter work fine (I don't work with AVI files, I wanted to encode straight to MPEG).
I converted an episode to SVCD (400 mb), but thought the quality was only ok. Out of curiosity, I did the same episode to VCD (300 mb) and couldn't really see much difference, if any. While SVCD is normally definitely superior, I think by reducing the bit-rate as I did it defeats the purpose somewhat of using SVCD.
Besides, it was a damn sight quicker using VCD, with, in this case, very little difference in quality!
Spy1, thanks for the link, their products look interesting. Next question is, how good are they?
