Just wanted to add that that I'm seeing a very similar problem, on
every channel change in liveTV mythfrontend crashes. Below is the
output from mythfrontend on one of the crashes;

I'm using TS mode for my DVB setup and have tried with & without
hwdecode enabled (no difference to the crashes). I plan on spending
some time this weekend on trying to get a debug build (I'm currently
using Axels Myth RPMs rebuilt with xvmcvld enabled). This is also
rebuilt with the av_remove_stream loop commented out of
avformatdecoder.cpp as discussed in a recent thread with Taylor and
others. I'll try with a stock 0.18 build just to be sure that isn't
causing the issue.

I'm not even sure if this is a myth problem or a Unichrome problem,
but I've seen numerous poeple on this list say their Epia's work ok
(at least without mythfrontend crashing) with 0.18.
