k, it ain't easy, here is the solution for ppl who want to turn .rmvb into a SVCD
First of all, you need Real Alternative 1.22, Streambox Ripper 2.009 and TMPGEnc Plus 2.5. Install of these program, start Streambox Ripper, drag the .rmvb onto the SR program, then exact the 'sounds' out of the file (movie likely), try to use .wav. Start TMPGENc Plus 2.5, select the .rmvb file (use the all of the files option under 'Files of Type'), then start the convertion process. Not the role Real Alternative played in this .rmvb to SVCD process, but you got to install it.
