I have used DVD Decrypter to extract the vob & ifo files from an NTSC DVD onto the PC and want to just convert them to PAL before burning them back. I don't want to lose quality so thought to convert to MPEG2 DVD PAL which worked, but file sizes were only a quarter of the original, so I assume quality has been lost. Certainly on looking at the result there are visible artefacts.

I then tried DV AVI and got inverted video, and AVI gets very upset. I also tried just doing the AVI without standards conversion, thinking I might need 2 passes to achieve the result, but this was the same.

Any suggestions/advice?

Many thanks

Chris
