[vdr] deinterlacing VDR-HD on xine?

Hello list,

after some unsuccesfull tests with HD-VDR on Ubuntu, I decided to return 
Opensuse (i'm using it for SD-VDR for about 4 years). I installed a 
fresh 11.2 x64 version, compiled v4l-dvb-b8eb9e860545 drivers, installed 
NVIDIA-Linux-x86_64-190.32, compiled xine-lib-1.2 
patched with xine-lib-1.2-vdpau-r284.diff by Reinhard Nissl, vdr-1.7.9 
with liemikuutio patch, vdr-xine-0.9.3 and PearlHD skin.
I had to make the following settings to have a tear-free HD video:
- give 512 MB RAM for onboard video (i have 8200 onboard on Asus M3N78-VM, 
- set cpu-freq to the max. possible value of 2.1 GHz (aka "performance 
governor") as i had problems letting cpu-freq to choose the cpu frequency 
(i don't understand, why, as i had no cpu load higher than 40% 
even on high bitrate HD channels) - AMD BE-2350
- disabling composite out in xorg.conf (I have a 1920x1080 LCD connected 
via dvi)
- and the usual settings in ~/.xine/config for buffer values

Now VDR works fine even on high bitrate channels with "xine  --post 
vdr_video --post vdr_audio --post upmix_mono --post vdr". The problem is, 
if I'm trying to activate deinterlacing in xine ( 
and many other tvtime setups) I end up with some dropped frames and 
freezes on high bitrate HD channels (>12mbps).

Is this issue coming from my hardware's limitations 
(not enough CPU or GPU power), or is there any more 
things to fine-tune?
