Up until now I have been using the S-Video output from my 921 to my analog TV. With the recent death and resurrection of my 5th 921 I started using the composite output (the S-Video now goes to an S-VHS deck so I can record all the DVR recordings I wanted to save before sending the old unit back). When I hooked up the new 921 (#6) the first thing I noticed was the menu appeared to be a little bit brighter. However once I started watching programming on the new unit I noticed that the video level was too strong, my picture sometimes ripples (including the browse-banner). I can do a temporary fix by switching to HD then back to SD. However within a few minutes the wiggle has returned. The S-Video signal does not appear to have the same problem - just the yellow RCA connectors. I called Tech Support who immediately sent out a replacement for the replacement ("lucky" #7). #7 was not so lucky - there is no difference the problem is still there. Before anyone says it's my TV - this same input was used for a DVD player and it did not overdrive. Also the 921 overdrove my VCR on the RCA inputs. So it's definitly a problem with the output of the 921. I'm just wondering if the software is to blame (L278). Not having used the yellow RCA outputs before I cannot say if prior versions had the same problem. Using the S-Video output I have noticed, from time to time, that the video level would sometimes change on menu screens (getting brighter and dimmer like there was a loose connection inside). I have seen that anomoly off and on through several software versions and several replacement 921's. Has anyone else seen this problem?
