<div class="moz-cite-prefix">I have been using mythtv and ubuntu
12.10 on my new machine since mid-January. I was running fine with
0.26. I was applying updates several times a week. I stopped
applying updates due to system crashes that set in (I have
resolved those, I think it was wine, which I removed). <br>
<br>
I had a backlog of encodings so it took me a while to notice this
problem. I strongly believe that it crept in around the middle of
February. I'll try to get a precise date this evening if I can
correlate when I recorded the shows. I don't know of apt-get keeps
a history of applied updates. If it does, I'll report back on
that.<br>
<br>
The movies originate as mpeg-2 transport streams. <br>
<br>
What I find VERY interesting is that before using mythtv, I was
experimenting using NextPVR on my Windows 7 box with the very same
channels and InfiinTV card. I would always have to run the
captured .ts files through Project-X (or some other tool) to clean
it up before Avidemux or Handbrake would touch it. <b>But on
occasion,</b> I got files that behaved the same as now:
Handbrake would report time sync issues, and Handbrake would
produce h.264 video that would play at almost 2x time and the
audio had lots of drop outs. Using VideoRedo would fix the
problem, except for the last two minutes of the recordings, where
it would revert to the bad behavior. My assumption was that I
overloaded the CPU (or I/O) with handbrake jobs. But, on my new
Ubuntu/mythtv setup I have never experienced any problem encoding
and recording at the same time. I will, of course, do a test with
no other activity on the system while recording.<br>

<pre wrap="">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?

<pre wrap="">
What version of MythTV were you running before this broke?
What format video are you capturing? You mentioned 1080i, but is it
mpeg2 or h.264?
This seems like it must be a recorder issue, but I'm not aware of much
going on in 0.26 with respect to recorders with the exception of the
HD-PVR.
