Yep, over the air 1080p is out of the question using mpeg-2. That's like trying to squeeze Roseanne Barr into Kate Moss' thong. Both end up being a real eyesore. 8-) Too much data to squeeze into too little bandwidth over too short a period of time (for real time delivery). Mpeg-4 could definitely get the job done though it would require a lot more processing grunt on the receiving end.

Cheers,
