I wish there was. I have the 722 and yes, the DVR rental interface feels like something out of the 80s. I have searched online for a listing of the 3000+ movies that are included in blockbuster @ home (like what instantwatcher.com does for Netflix). No such luck.
Gotta have time to spare when trying to find something good to rent via DVR.
