Anyone who's used it knows this, but Last night I found it could do something I didn't expect. I had to return a dvd - but we hadn't got around to watching it yet.. so I was like "aaaagh, I'll rip it". So I ripped the raw vob's and decided to compress it later, as I had to pop the dvd back before the shop closed.
When I got back I thought.. hmmm.. I wonder. So I transferred the vob's and the ifo to my xbox hdd, booted up XBMP and what do you know - media player plays VOB's, and MY GOD the quality is nice. So with a 80gb hdd it works out as a nice way to hold on to movies you like for a little bit longer, enjoy them in high qual, and return them - when you can later compress them, or delete them.
I'm not sure about the sound - as the direct rip thingie says it can rip 5.1 but I dunno if this works in theory. This movie was a drama so it didn't matter too much. Anyway, I was stoked about that, so thought I'd pass it on.
Yay XBMP! You rock!
