I just got a new directv hd dvr hooked up and am wondering what is the best way to send the signal to a second tv. I have used coax in the past, but that is not possible with this receiver. I read in another thread here that all of the
'out' ports are always active on the receiver, so here is my setup and ?:

I plan to go from dtv rec to older hdtv in same room using component cable. That leaves me with s-video or rca ports to connect to a sdtv in another room. I estimate the length of cable needed will be 50'. The picture quality to the sdtv is not paramount, but I do want to use the best possible method, as I will be running the cable thru the attic, and as we all know, attics are not fun.

Thanks for any advice
