But Xine does!

Hello list,
I am heading to install a TV and PVR on a VIA Epia ME6000 and
using onboard hardware acceleration (CLE 266). I use a DVB-T capture
card (TechniSat AirStar 2TV).
I installed Fedora Core 2 with kernel 2.6.10-1.8_FC2.
I applied the kernel-via-drm from Terry Barnaby´s site
(http://www.kingcot.eclipse.co.uk/unichrome/fc2/)
and most of the new xorg-x11 rpms from here:
http://washington.kelkoo.net/epia/FC2/RPMS/
I have installed
xine-lib-1.0.0-999.1.beam.rc7.fc2.i386.rpm
from
http://www.kingcot.eclipse.co.uk/unichrome/
(after I have solved the dependencies).
Now Xine is able to play DVD very well and using hw acc.
But I still struggle with MythTV 0.17. The CPU usage is very high
(mythfrontend ~50%, total ~92%) and I get a very choppy life stream when
watching TV.
I have compiled it with XvMC support, enabled XvMC_VLD support in "settings.pro" (and NOT nvidia-XvMC)
In mythfrontend´s settings I can select
"use hardware XvMC MPEG Decoding"
and
"Use HW XVMC VLC Decoding (Via only)"
I have already tried all sorts of combination (one or the other on, both
on or none) and there is no difference in performance and log messages.
When I start "live TV" in mythfrontend I get no messages in console that
XvMC is being used.
First I was asking in the Unichrome list
(http://sourceforge.net/mailarchive/forum.php?thread_id=6926603&forum_id=38837) but then I was told it is a Myth issue...
So find much more details (logs, settings, suggestions, results,...) there.
Does anyone have an idea what I did wrong??
Thanks for help
Raimund
