use DVR instead of RF splitter??

Does a DVR (in my case, Panny E85) passively move any RF signal from coax in to coax out?

I ask because the DVR doesn't handle HD, but my HDTV's built-in tuner does. Is the DVR going to alter the signal or prevent the HDTV from grabbing HD b'casts? (I'm using a rooftop antenna and not trying to record HD, just watch.) If it's a problem, I'd get a splitter and avoid the E85's coax out.

To the best of my knowledge the Coax (IN/OUT) of DVD Recorders are all passive. When I was new to using a DVD Recorder to record programs (when I was using my first one, the Toshiba D-R1) I thought you hooked it up the same way you would a VCR and used the Coax connections to hook it up to my TV.

When I was receiving no picture (or first time use on screen instructions) I thought I had a defective unit...but I didn't. When I finally connected it to my TV using the RCA (Yellow, Red & White) connections I was able to view the on screen displays and it worked fine ever since.

Now I have one with a Hard Drive in it (Pioneer 640) and I don't even use the Coax OUT, just the IN to receive cable.

I use the RF in/out connectors as a loop-thru with no problems on my Pana DMR's and on a pair of Sony RDR-GX300's. Works great! Saves money too (no splitter).

I have my OTA antenna going into the Panny E80H then passing through to my Westy 32" HDTV. HDTV signals come in just fine on the TV and the panny picks up the snowy analog.

That's great. I just need to find or buy another coax cable.

On that subject, I was "surprised" to find the "old" RG59 cable (I think that's the number) still around at Walt-Mart, right next to the "good stuff" (RG6)Q

for short runs RG59/RG6 should make no difference, so it doesn't seem that strange to see it in a place like Wal-Mart. RG6 is thicker and harder to work with and if we are talking 6-12 foot lenghts, it shouldn't make that much of a difference. (if any)

What do you mean by "loop thru"??? I have splitters that i'd love to get rid off! Thanks

The RF Out of most DVD Recorders functions as a splitter, passing through whatever is present on the RF In.

Thanks! I thought (wished) "loop thru" was some other trick I didn't know about

Some of them modulate, but they are rare. For example, the Centrios 8020 modulates out of the RF. It is not a pass-through only.
