I will give some of these suggestions a try this week - I have 3
pchdtv boards and the goal is to have the noisemaker server machine(s)

I get broadcast HDTV in 1088, 480p and I think some 720p.
There maybe a couple different bitrates for the 1080i (WB/CBS is
highest bitrate at 7.5GB/hour, NBC was 5.5 GB/hour).
