[mythtv-users] Help - Myth freezes my system

[awrobinson at nc.rr.com]

I'm trying to build my first MythTV system. I'm using FC4 on a system
with an AMD Sempron 3000+ socket 739, an ASUS A8N motherboard and a
Hauppauge 250 capture card. I'm following Jerod Wilson's instuctions
from his Fedora Myth(ology) page. I've done all of the checks along the
way. I can watch TV with ivtv and mplayer. I can record with ivtvctl and
'cat /dev/video0'. Everything in Myth seems to go fine until I click on
"Watch TV" in the Myth frontend. At that point, my screen goes blank and
I get no response from the mouse and keyboard. I can ssh into the system
from another on my network. I can kill the Mythfrontend process and the
kdeinit process, but I do not recover responsiveness on the myth system
until I reboot it. While the user interface is completely frozen, the
video is being recorded in a file in the directory I've specified,
/av/video. I've include the output from Mythfrontend below. There is
nothing in it that jumps out at me. Can anyone provide some clue as to
what I'm doing wrong or how I can figure out how to fix it?

Thanks!
