After a recent upgrade to my MythTV backend and adding a new video card, as well as improving my cabling setup, I started seeing glitches in some, but not all, recordings. It's easier to show them than to describe them:
http://home.comcast.net/~cvargas12/problem-example.jpg It's a horizontal "tugging" of some lines, most visible at the edges of the recordings.They seem to increase or decrease in number depending on the image being displayed. I don't think this is a cabling issue: I've reduced the number of feeds from the single cable run, put a higher-quality splitter in place, the problem is not consistent, and the TVs I have connected to the same cable feed do not show the same glitches. I guess it could be an increased heat issue with the addition of the video card, but it's interesting that (again) it's not consistent. I did upgrade to the latest ivtv drivers with no change in the problem. Hopefully it will look or sound familiar to someone who can provide some ideas on how to fix the problem. Thanks. ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.10.3 (tagged release) loading ivtv: Linux version: 2.6.18-chw-13 SMP preempt mod_unload 586 gcc-4.1 ivtv: In
