Well, since the price of a CM 7000 has gotten so low and since I had coupons still, I went ahead and ordered one. It arrived with the expected pros and cons: like great reception (pro) and ridiculously unreadably small on-screen-text (con).
The reason I'm here is because Delphin had written about the difference in composite output from these boxes. With previous CECBs, I had gone to different televisions around the house, and flipped back and forth between RF (channel 3/4) and RCA jack (composite) signals. Frankly, the RF inputs were almost indistinguishable from the composite. I really had to spend time studying the screen to spot the difference.
The CM 7000 is unlike any other CECB I've used. The RF input is horrible. The screen shows a lot of interference. (Like setting your DVD player to output on channel 3, even though there is a channel 3 in the area.) On the chance CM sent me a bum cable, I tried the cables from the other CECBs. No improvement.
This matters to me because so far I'd been hooking up the CECBs through the RF, and the DVD/VCRs through the composite. It's an easier set up for me, both in use and when changing out equipment. That set up will not be possible with this CM 7000. The RF picture is really unusable.
So I'm asking, has anyone else compared RF/coax and composite picture quality? Did I get a bum box, or this (another) limitation in the CM 7000?
Thanks for any info.
