Sorry if this question gets repetitive, but I can't find the exact solution/answer to my problem. I used DVD Shrink and DVD decryptor separately to rip my DVD that contains VOB files, because one of the episodes I had one their was troublesome. When I rip it though, and try to re-author it using Roxio's DVD Builder, the video and audio are out of sync, but when I burned it to a DVD there was no problem...can anyone help?

Also, the same dvd burned later start to pixelate? It's quite irritating. I'm not sure if this is because I used "automatic compression"? But if I were to use low-compression, it'll only allow me to burn 3 episodes worth, 75 min., so should would it be any better using Nero instead. Any input would be nice, thanks.
