I had my Tivo set to record at 352x480 1840kbps with 32khz 192kbps audio. I want to find a tool to let me convert to 480x480 2376kbps with 44.1khz 224kpbs audio. This is the standard SVCD setup. I also hope to be able to adjust the video size so that it can fit on a CD.

Most of the tools I have found are intended to convert a DVD to SVCD which makes assumptions on input resolution and audio rate.
