I have currently  a spare Core2Duo machine. I made a test setup for 
mythtv with valgrind.
The System is setup using *mythubuntu 8.10* with latest weekly build of 
mythtv.

MythTV Version   : 19626
MythTV Branch    : branches/release-0-21-fixes
Library API      : 0.21.20080304-1
Network Protocol : 40
Options compiled in: linux profile using_oss using_alsa using_arts 
using_jack using_backend
using_dbox2 using_dvb using_firewire using_frontend using_hdhomerun 
using_iptv using_ivtv
using_joystick_menu using_libfftw3 using_lirc using_opengl_vsync 
using_opengl_video using_v4l
using_x11 using_xrandr using_xv using_xvmc  using_xvmcw using_xvmc_vld 
using_glx_proc_addr_arb
using_bindings_perl using_bindings_python using_opengl 
using_ffmpeg_threads using_libavc_5_3
using_live

I still have the usual memory growth of about 100MB per Hour.

*After Start:*
PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  
COMMAND           
18276 mythtv    20   0  326m  97m  11m S    2  4.8   0:07.08 
mythbackend       

*2 hours later*
ID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  
COMMAND           
18276 mythtv    20   0  545m 338m  11m S    1 16.7   3:17.69 mythbackend

I did a 1hour recording and a 5minute recording, both with valgrind running.
(The Reports are attatched to the Ticket #5545)

As it is a test setup without any personal data on the machine I offer 
to put the machine into a dedicated subnet accessible
from the internet and pass the login to a developer if it helps to 
figure out the source for the memory growth.

Best Wishes
Andreas
