Ok, this is ridiculous, but for the life of me, I can't figure out how to hook up my dvd recorder to my digital cable box + HDTV setup.
First off, my entertainment center is one of those beasts that takes up an entire wall, so it's hard to get to the connections. I used to have much less stuff

Anyway, the cable is split right from the wall, one line going to my router, the other, to the set-top box. Box hooked up to TV via HDMI. No issues there.
Box also running a coax out into DVD recorder's input. Tried running the recorder's outs to the TV via s-vid, then component, w/ stereo a/vs for audio as well. The recorder not picking up any channels with either, auto or manually. Tried setting the cable box to chan. 3, changed all sorts of TV input... gotta be not decoding the digital signal from the box?
Recorder manual's only option was a crappy schematic showing a splitter from the wall running straight into the recorder... but then I'd be splitting it twice right from the wall, and the installer already said just one would degrade my signal...
I just want to record some shows. I'm still in my 30s. This shouldn't be happening to me yet.
Help appreciated!
