It may depend on the local station and/or the program.
I've never recorded much ABC in HD because I couldn't
play it. But simply looking at the 1hr Lost episode I recorded,
its about 6GB, when a 1HR CSI or something on CBS is almost
8GB, so clearly there's more there.  NBC is shows, ER for example
is about 5.5GB/hr.  All this is OTA receptions in the local MSP market.
I have very little info on the local Fox, but they usually split
their signal in 2 subchannels.

My working theory is I need to fool Myth into thinking its got
a 8GB/hr bitrate, so it sizes the buffers everything accordingly.
Maybe far off base...
