We just had Comcast upgrade one of our digital boxes to HD for a new Sony XBR8 46". The cable box they put in is the RNG110 - it is the cheapest looking piece of equipment I've ever seen, nothing like the grey Motorola box that was there before and that we have on our other high def TV. The Comcast installer indicated this is the "latest and greatest", but the equipment looks like junk and the high def picture is very poor. My questions are:

1. Is the RNG110 Comcast's latest and greatest, or did they just stick us with a low-end piece of junk

2. Any advice on getting better HD out of the RNG110? I just brought up the diagnostics, and the OOB signal level is red at -18 -- does the OOB signal affect high def picture quality?

I cannot answer your questions, but will tell you that I had two different RNG 110 STBs. Although they both initially provided clear HD pictures, they both failed in less than one week. The last tech guy that came out said the RNG 110 must not be a HD box?!?! WTF?

How to bring up Diag for the box ?

How to bring up Diag for the box ?

It's been a while, but if memory serves you first power off the 110, then quickly hit the "Info" button.

You can also power off and then hit the "Menu" button and it should allow you configure the box (aspect ratio, Closed Captions, etc).

Hopefully I have the buttons correct above since this is from memory
