[mythtv-users] Really bad prebuffering pauses

Wondering if anyone could help me out here.
I've got one frontend that is suffering really badly from pauses, in
order (worst first) the circumstances are:
- watching a recording of something that is still in progress
- live TV
- watching a recording
Not all recordings are affected to the same degree - I think lower res
recordings skip less.
I've got 2 stand-alone frontends and a combined front/backend - it's
only one of the standalone frontends that is affected, here are the
specs of that machine:
P4 3.0 Ghz Hyperthreading on turned on.
GeForce4 MX 440 AGP (using nvidia legacy driver 96.43.05)
MAudio Revolution 7.1
All shows are recorded from UK DVB-T without any transcoding.
Top shows that during playback, ~30% CPU is used. I've tried various
playback CPU profiles, but none seem to have a dramatic effect -
'Normal' is currently selected.
Here is the info from mythfrontend --version:
MythTV Version : 17961M
MythTV Branch : branches/release-0-21-fixes
Library API : 0.21.20080304-1

using_xvmc_vld using_glx_proc_addr_arb using_bindings_perl
using_bindings_python using_opengl using_ffmpeg_threads
I've attached a snippet of logs in the hope that there is some useful output.
I'd be really grateful for any assistance sorting this out.
Thanks in advance,
