Which program to rip with DVD2SVCD?

Just a little background info for the curious ones ;) The thing is I have 2 rips on my HD but my PC is a celeron 466 which is not supported by CCE, that's why I transport my HD from one PC to the other to convert. Since I'm running out of space I need to convert them (no space, no more rips) and I can't wait till next month:D Again, thanks for all the help.
