Hi list, I seem to have the same problem that Chris Vargas wrote about in a message to this list a few days ago:
http://www.gossamer-threads.com/lists/ivtv/users/35932 Basically there seems to be a problem with the horizontal sync in the ivtv tuner code (?). Here's a screenshot: http://ward.vandewege.net/horiz_sync_problem_ivtv.jpg This is on ivtv 0.10.3, with MythTV 0.20, and the card is an older PVR-350 PAL version, which has worked fine for several years. Older recordings (made with 0.7.0) still play fine without these artefacts. All new recordings are like the above, as is watching live TV. Sometimes there are short fragments where the sync issue is not as bad. The sync issue is always identical when playing a recording repeatedly; the data has been recorded badly, playback seems just fine. I was running ivtv 0.7.0 without problems, and when I upgraded to 0.10.0 in March, I hit the driver issue with vertical syncronization, see this thread: http://www.gossamer-threads.com/lists/ivtv/devel/35290?do=post_view_threaded This resulted in a black bar at the top 1/3 of the screen when changing channels. That got fixed in 0.10.1 (the black bar is now removed in a fraction of a second), but the horizontal sync issue remains (I've tested 0.10.1 and 0.10.3). Any thoughts? The dmesg output follows below.
