[mythtv-users] Seg fault when using cle266

I have been trying to get my myth system up and running for a few weeks now,
but keep hitting the same problem.
With the cle266 lines hashed out, the system runs ok, except that watching
live tv or recordings is unwatchably stuttery with prebuffering pauses.
Compiles with cle266 enabled, mythfrontend segfaults a few seconds after
selecting watch tv:

System is a Epia M10000 Nehemiah with a PVR350.
I originally installed using Fedora core 1 and version 0.14 and got this
problem.
I have now installed gentoo, with kernel 2.4.25-epia1-r1 and xfree-epia
4.3.99.902-r7, generally following the guide at
http://www.alterself.com/~epia/wiki/tiki-index.php
I also have libddmpeg installed from ebuild
I have installed 0.14 from ebuilds and tarballs, and now 0.15 from CVS, and
always get the same problem.
Is there some step/install I am missing somewhere?
I did get the TVout on the PVR working at one point using fedora, but really
want to be able to use mythgame, etc

Why does playback use so much CPU power anyway? Playing the same recorded
file uses 30% cpu using mplayer(+libmpeg2) where mythfrontend uses 80-85%
and doesn't cope.

TIA for any pointers
