[mythtv-users] Stutter every 15 secs

[john roberts]

Thanks Doug!

Well - I did the upgrade and I would say the 15sec record issue went away.  So this is good!

The ATSC watching seems to have taken a few steps back IMHO.  I've been watching ATSC content for about 4-5 months now and I think the current CVS tree has some things broken.

For one - when you would go to a station which was weak - it used to back out and go to the previous station.  It now hangs with an error about not getting data from the card and says "Game over man!" :)

Anyway - I have to stop the frontend - reset the card to a known good station with dtvsignal and it works again.

I'm also having an issue with my only 720p content station.  Signal seems strong - but it plays for about 2 sec's and stops with a black screen.  Kinda odd.

Anyway - appreciate the help - and thanks again,

-John
