[mythtv-users] Channel change failure on HDHR

[R KANNAN]

Hello,

I am using Myth with HDHR.Most of the time it seems to work fine. But
sometime a recording fails when it fails to change channel. The backend log
shows


   1. 2011-12-28 20:58:01.771 TVRec(3): Changing from None to RecordingOnly
   2. 2011-12-28 20:58:01.809 TVRec(3): HW Tuner: 3->3

   16. 2011-12-28 21:02:00.809 TVRec(1): Changing from RecordingOnly to None

I don't care about this particular recording but sometimes it happens to an
episode that I want to watch :-(

Any ideas on how to debug this?

Thanks
