I’ve always used dvdrip to rip DVD’s to AVI

I stream them to my ps2 using BroadQ (now gone!)

It works with 1 minor, annoying, problem. BroadQ doesn’t support lots of resolutions that are in use out there, so while I can watch my DVD archive, I can’t watch things like sample videos I download off the net and stuff… so I’m installing ripmake, which looks like an awesome tool to handle the job of re-encoding files easily and painlessly…
