The last time I checked my understanding was that people should set
their cable boxes to output only 720p, as 1080i encoding had major
issues. Has that changed, or is that only a problem stil with some
people' setups, like jedi's?

On that note, I've yet to see any 1080i sample HD-PVR clips. Anyone
know of one publicly avalable?
