Don't worry about the recap I had it in my bin and pulled it out.

I'm a little confused.

You seem to be talking about over the air muxing of analog channels?
My understanding of US OTA broadcast was it was using DVB-T where
cahnnels were muxed (so a HVR 2250 card would be ideal).  I'm not
aware of any analog OTA muxing?
