[mythtv-users] Regression? 0.26+20130221 Time sync issues

For some time now I have been capturing HD movies with mythtv, trimming
them with Avidemux 2.5.6 and the encoding with Handbrake. About a week
ago I applied 2:0.26.0+fixes.20130221.c3fff6e-0ubuntu0mythbuntu2 amd64.
Now the resulting .mkv files are unusable. The audio and video are sped
up and jerky. Handbrake reports many sync: audio time went backwards and
other errors, resulting a numerous dropped frames. Viewing the .mpgs in
Avidemux exhibits some audio problems.
Unrelated to this problem is that I have always found the audio in
Avidemux and Handbrake to be ~750ms out of sync and constant.
I'm using an InfiniTV PCIe device with cablecard and 1088i mpeg
transport stream content. I have a quad core 3.4GHz box. I am just
beginning to analyze the problem. I tried the latest updates last night
and the problem is still present. I'll see if I can find an older update
to try (I would rather not rebuild it myself). If it is indeed a mythtv
issue, then it should have crept in fairly recently since I had been
applying frequent updates.
Any other thoughts about how to resolve this?
