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.

Thanks,
Ward.
