    Thanks to the "What the latest deals are" thread, I called up DirecTV and, after some nudging, got the HR20 for s/h + tax (~$21). The Installer came out yesterday and, with a little help from me to make things go faster, he installed the dish and the HR20-100 with no issues.

    However, I'm currently having problems linking two TVs in different rooms together using the same HR20 output.

    As background, I pre-wired my rooms with two coax outputs and have an equipment closet where all runs feed into...the multiswitch is there as well. With the old D* Tivo unit, I used a diplexer to get the signal from RF Out on the unit through the wall to the multiswitch and another diplexer from the multiswitch through a different wall to my second TV. I controled the channels using an RF extender and it worked perfect.

    Now, with no RF Out on the HR20, I'm having some trouble. I've read about using a RF Modulator and I've read the "Connecting Multiple TVs" pdf, but I'm trying to figure out if that will work in my situation, and why my current alternative won't work.

    My idea was to use my existing DVD player, which has an RF Out, in the same capacity as the RF Modulator. I ran the S-Video and Audio cables from the HR20 to the DVD player and a coax from the RF Out on the DVD player to the Diplexer. I have the same wiring and setup as before using the diplexers. However, the video and audio come through on the second TV but appear scrambled.

    Any thoughts on why the signal is coming through scrambled? Does the RF Modulator do something else that my DVD player doesn't? Lastly, if I need an RF Modulator, I assume I can still use the diplexer setup to get the signals through the walls as described above?

    I don't know if this is an option for you, but you can use CAT5 cable to create an SVIDEO cable. Just buy the SVIDEO adapters from Leviton, available at Home Depot.

    The HR20 remote can be used in RF mode, so all you need to do is figure out the sound...

    I have had that same issue before, scrambled images being fed through a DVD recorder. The DVD recorder's DRM circuitry was preventing it. I bypassed the recorder and everything was fine. FWIW

    As nearly free as they are would you consider ordering a second HR20? Sounds like you have the the wiring to do it...:)

    Have you try to change resolution on the HR20 to 480i or 480p.

    I wondered if it might have had something to do with the DVD Player/Recorder. As mentioned, I was trying to use it similar to a RF Modulator.

    However, I decided to try another (old) VCR in a similar manner and it worked!!! I ran the composite cables into it and used its RF Out to run coax to the diplexer...related to that, I still used the diplexer set up I mentioned above. I can now watch TV in the other room controlling the HR20 with the remote in RF mode. :hurah:

    Thanks for all the input.
