Glad you got it working. But honestly, unless coax is the only input, don't bother using coax. It outputs audio in mono and the pq is the lowest of all outputs. I connect TV2 from my 722K using composite cables (r/w/y). You can find high quality cable sets from monoprice.com that come in very long runs. I use a 25' set that has the video cable (yellow) made from RG59 cable. And they sell better sets that use RG6 cable. I've experienced no problems with these and they aren't much more difficult to run than coax.dcb said:Thanks for everyone's help. With your hints and reading my manual closer, I overcame my ignorance and have it working great.
