snipes go most everything right, especially with the links, few differences
you need DVD2Xbox (not Xbox2DVD

) to copy games and DVD's
grab it in our files section here at SMDepot
As far as ripping it on the Mac, you'll need an app called
Handbrake i have personally never used it but i hear goodthings
IF you have a Windows OR Linux machine around you can run
DVDFab which is what i use (use Wine in Linux)
DVD2Xbox can only handle CSS encryption, not Sony ACCROSS, the new one, Handbrake should be able to handle anything, DVDFab can
On another note, you can get the xbox to output 1080i with an HD cable (sorry no 1080p) that you can get off ebay im sure. Then just make sure the option is set in the settings, otherwise your watching it at 480p no matter what you have it plugged into
