I'll bow to your superior knowledge on this matter but for the sake of
clarification I'd appreciate your reply to my questions below.

I agree that keeping PVR capabilities whilst achieving speeds equivalent to
those which are already accepted in current TVs is the best goal. Is that
achievable though?!? Maybe I grab the wrong end of the end, but people seem
to suggest that the buffering/ringcache is responsible for most of the delay
and now that eliminating it can't be done? So is the real limitation the
TV-though-PC model? Are the TV cards themselves the flaw?
