A few questions...
The PS3 only outputs in 720P and not 1080i?
Your TV is an HDTV but doesn't allow 720p input?
How do you watch Fox-HD or ABC-HD, they are both 720p HD channels, iirc?
I have a 720p TV, but it accepts 1080i also and just converts it to 720p...I thought most HDTV's worked this way...
