Sharing wise, unless you have a big upload then do xvids. I too use normal gknot (go to the doom9 forums for the latest version), its pretty straightforward if you don't deviate from the guides until you know what everything does
For personal backups, there's only one option DVDr wise. DVDRebuilder. Superior quality everytime. Its slightly slower than transcoders but worth it. Also available in the doom9 forums
