low quality ==> high quality?

[kbd]

I just happen to get a copy of "The Ring" from a DVD, but appearantly the DVD was a cheap type, therefore the quality of the movie is even lower the VCD (not SVCD). Basically, the quality is bad, really bad. I just ripped it out and planning to convert it to SVCD but does not want that low quality. Is there anyway or any program that i can use to sharpen up the pictures (better quality) as well as the audio a little? If so, please show me how.

I'm using SmartRipper, DVD2AVI, TMPGEnc Plus, and VCDEasy to go from DVD to SVCD if any one want to know.
I was thinking of using TMPGEnc to do multi-pass w/ VBR but since the quality are already bad, some part will be even worst.

Once the quality is gone you can't get it back. But you can make it look a little better. Run lots of noise reduction and then blur. This takes out alot of macroblocks that low bitrate movies have.
