I'm running Mandrake 10 Official, with thacs.rpms as the mythtv source.

Runs flawlessly (after some initial fun with funky behavior (mythconverg
related I think) that seems to have "fixed itself" with the default
kernel, was also running cooker with same kernel, 2.6.3-7mdk. Tried a
custom compiled with only K7 and preemptive changed, the preemptive did
BAD_Things to recording when running interactive programs (backend is
also main "box", as it appears to give the X et al the ability to
preempt recording I/O which is or needs to be a real time

Running Nvidia 5336 drivers, not using TVout on my GF4 MX 400 as I have
an Xbox for the main frontend, which took adding one line to the sources
list, and an "apt-get install mythfrontend mythdvd mythvideo
mythweather" to get 0.15 up and going on.

Mythmusic had a dep conflict with an alsa lib, I decided to jack with it
later.(Using xbox-mythtv 0.4.1, may not be an issue on 0.4.3)

May be an FC1/2 issue, or something ivtv related, but it's NOT Mandrake.
