Yes and he is absolutely right. Over the air pbs 1080i is going to look better than a 1080p blu-ray or hd-dvd because it is uncompressed (or nearly) the bandwidth each station has is unreal. Now goin through cable or satellite the BRD or HDDVD is gonna win cause the compression is usually lower.
Some research turned up this:
|In the US, HD is broadcast over the air in a 6MHz wide channel at
between 19-20 Mbps (3 bits/symbol). However, that 20 Mbps stream can
be divvied up in lots of ways: 1 really HD channel, 5 SD channels, 2
SD channels plus a medium rate HD channel...
Compressed digital video that is intended for further editing is also
compressed differently, because the "broadcast" compressions tend to
have unsuitable artifacts in the editing process. Squeezing a raw
data rate of >1 Gbps down into 20 Mbps or so always entails some
compromises, and the broadcast compressions are designed to allow
inexpensive decoders (and expensive encoders..you'll be making
millions of decoders and dozens of encoders) and for artifacts that
are visually unobjectionable to an end user.
