That *is* curious. Using my OTA HD capture card, changes take 3-5
seconds from pushing the enter key on the remote. While we both run
combined frontend/backend boxes, your Opteron trumps my Pentium
4. While both signals are MPEG-2 digital, I am getting 1920x1080 HD
over ATSC while you are getting . . . Well, much, much less than that
over DVB-T.
