I have a Dave Matthews concert on DVD (this is legal to make copies, he allows people to tape his shows) and I want to put it into .mpg or .avi or possibly even .wma so I can share these files on the internet. How do I do it? (Shareware/freeware preferred) Whats the best compression method? It doesn't have to be great quality, so the lowest Mb per second would be best! What format should I use to share with PC users also?
