I was watching it yesterday, and noticed the CPU consumption was out of whack.
I was seeing about 10% at idle, and 70% of a 2.8GHz core with one file playing back.
(This is without any transcode/commflag jobs or anything else running on the machine)
Seeing 70% << 100%, I didn't think much of it. ;-)
I'm seeing the same phenomenon with my 0.26+fixes backend (MythBuntu 12.04). 105%-120% cpu while the PVR Manager is starting up and loading recordings, and for about five minutes after. (The MythTV backend is dual-core.) About 70% cpu while playing a recording, and this goes to about 4% while playing a recording after rebooting the backend.
If you Google "mythbackend high cpu" you'll find some reports of this, but most relate to a leap second that was inserted last summer, so not the same problem.
One post recommended " If you open MythTVBackend -> Capture Cards -> DVB card -> Record options and then untick the "Actively Scan for EIT Data" box, it should work." I'm not sure if this is relevant, but I have tried it and will report back.
