[mythtv-users] DirecTV - only one channel at a time?

[Chris Hoelscher]

I'm gathering my parts and getting excited, but as a DirecTV customer,
was wondering - it sounds like I'm limited to just a single channel
input at a time, coming out of the RCA DRD430RG receiver.  I see where I
can cobble a serial cable to change channels, but I'm guessing I don't
need a TV Tuner card, just a capture card with this?  

Thanks from a noob....
