[mythtv-users] Mythtranscode failing?

[Eric Ladner]

While playing around with my transcode profiles, I ran across a bug, I think.

When trying to transcode 1080i (output from a HD-PVR) to MPEG-4, I get
a lot of audio warnings with some large offsets in milliseconds.
Eventually, after about 10 or 15 min, it just gives up and errors out.

The audio is set to MPG with about middling parameters.  Going to try
a different audio decoder to see if that makes a difference.

In the mean time, has anybody else seen this problem?
