#10428: mythbackend logs RingBuf-messages every few seconds while playing LiveTV

After upgrading from 0.24-fixes to master/0.25, the backend continuously
writes out RingBuf log messages about it waiting for data:
{{{
mythbackend[9601]: RingBuf(/data/mythtv/livetv/1001_20120310153618.mpg):
Waited 1.0 seconds for data #012#011#011#011to become available... 130980
< 196608
}}}
While it does this, LiveTV works fine with no stuttering. The issue seems
consistent on all channels in LiveTV and playing back recordings does NOT
give the RingBuf logs. Eg. playing back any recording - even the just-
recorded LiveTV recording from the recordings menu - does NOT cause the
backend to write out these messages.
Logs from ~5 minutes of LiveTV playback is attached. If more verbose logs
are required to identify the issue, I'll be happy to provide them.
The tuner is a European HDHR dual DVB-C tuner. The backend is a 3.4GHz
Core i5 with 12GB RAM and database+OS on a SSD, so it seems unlikely that
this is a local performance issue.
