[mythtv-users] How does backend/frontend work with Directv?

[Joel Feenstra]

I only have one machine, but the serial connection works great. The only 
problem is that the directv channel display shows up at the beginning of 
recordings, but only for a second. I did have to modify the RCA.pl 
script to send the correct command for my box (it's a bit old). Then I 
just put the script as the external command. It comes in through the 
composite on my AverTV Studio, and sound goes into the little input they 
have on the tuner card.
