Hi Martin,
Can you try the following:
1) upgrade to the latest ivtv trunk as there have been some new vbi
fixes.
2) tune to your favorite channel using ivtv-tune.
3) run v4l2-ctl -c stream_vbi_format=1 -b teletext,wss
4) run cat /dev/video0 >test.mpg
Let it run for awhile and check with 'ps-analyzer test.mpg' whether the
stream is valid or not. If not, then keep the test.mpg and mail me the
output of the ps-analyzer run. I'll get back to you with more
instructions.
If it all works, then try the same with two recordings at the same time
and make the same checks.
If that also works, then try to use MythTV again.
Oh, and if you do get errors from ps-analyzer, then also look at your
kernel log if there are any ivtv messages (such as DMA errors for
example).
Regards,
Hans
