or alternatively get an hdtv and dl them via xbox live.
they are fairly hefty at 6 approx gigs each and are only rented ie once you watch they disappear.
They cost about �100 or so.....not too sure where to pick one up, but seeing as HD-DVD looks like it'll be heading out the door pretty soon, i'd advise you to hold back and wait to get a Blu-Ray player!
