Alright, so I think I'm set. Using all of the discussion on this thread, here's my plan:
The roof-mounted TV antenna coax cable comes into my house and, about 20 feet inside the house hits its first splitter. I will replace that splitter with a distribution amplifier with two outputs. The only thing I haven't told y'all yet is that after this first splitter (which splits the coax into 2 output coax), one output coax goes to the DTV/DVD recorder in the kitchen, and the 2nd output coax goes to another splitter: the 2 output coax's from this 2nd splitter go to the DTV/VCR in my living room, and the other coax output travels a very short distance from the 2nd splitter to an old CRT TV/DVD recorder (with only an NTSC tuner) in the basement. I believe that 2nd splitter is behind a wall in the basement (I couldn't actually see it, so this is my guess).
Question #1: am I good with using just the one, 2-output distribution amp using the above configuration?
For the basement CRT TV + analog-receiving DVD Recorder, I already just run the coax to the CECB -> DVD recorder -> CRT TV. For the two DTV's (LCD TVs, each with ATSC tuners) upstairs, I will buy the Zinwell ZAT-970A (two of them) and run the coax near the DTV/VCR (or DVD recorder) through the CECB, with the APT on the RF output of the CECB to connect to my DTV (using RCA cable?) and the RF output on the CECB to connect to the VCR (or DVD recorder) using RCA cable. I currently connect the VCR (and DVD recorder) to the DTV's using an HDMI cable.
Question #2: did I get the above right?
Question #3: can I continue to use the HDMI cables to connect the VCR and DVR recorder to their respective DTV's? You guys seem to be indicating in your posts that I need to connect the VCR and DVD recorder to the DTVs to the DTVs using an RF cable, so I am a bit confused on this part.
Thanks again...this has been an education for me and I sure appreciate this helpful community!
