[mythtv-users] Error: offset>181?

[DaveD]

Can someone tell me what causes this:

DVBRead mpeg/mpegstreamdata.cpp:362 (AssemblePSIP) - Error: offset>181, 
pes length & current cannot be queried

It shows up in the backend log during recording and results in a few 
seconds of corruption in the recording.  It happens very rarely on most 
channels, but on one channel (of course, my favorite, PBS) it is 
extremely chronic.  This is the only 720p channel I record.  All the 
rest are 1080i or standard def.  Some of the PBS recordings are 
error-free, but more are corrupted periodically, every 20-40 seconds, 
all the way through.  I believe all content on this channel is 720p.

I never saw this problem in 0.24 (FC13), only after upgrade to Fedora 17 
and 0.25 (mythbackend version: fixes/0.25 [0.25.2-2.fc17 
(v0.25.2-15-g46cab93)]).

Google turned up a few hits with this error, but it seemed to only be 
related to HDHomeruns, and seemed to be signal.  I'm using an internal 
Dvico Dual Fusion.  My backend is not overloaded and has no trouble 
recording two 1080i shows while playing back recordings with no 
corruption whatsoever.  A single, system-doing-nothing-else recording on 
the 720p, PBS channel is more likely to be corrupted than not.  I was 
surprised, though, as I looked through my PBS recordings, that some of 
the shows are perfect, but shows recorded soon before (or after) were 
corrupt.  It seems to be content-related.

Any ideas?  Is this a known issue?  Will 0.26 upgrade fix it?
