[mythtv-users] System hangs when scrolling thru a menu

[nowhere at cox.net]

I assembled my new mythbox and installed myth last night and all was working very well (both TVcards, recording, liveTV, weather etc...). Many thanks to Jarod for his exceptional guide! I do have one rather severe problem however.  

When scrolling down in the "Fix Scheduling Conflict" menu with a couple dozen shows queued (no actual conflicts btw), my frontend will hang completely, requiring a hard reset to continue. It always occurs once the last item in the menu appears at the bottom slot of the displayed items.  Occasionally it will hang up if I simply scroll up and down in the middle of the list. The hang is simply that the PC will no longer take any input. I cannot esc out with remote or keyboard and ctrl-alt-del will not give me the logout option. The screen remains with the last state myth was in before the hang. It does not go black or distort in anyway.

Hardware:
Athlon XP2000+
Corsair 512MB
Seagate 7200 80GB HD
MSI K7N2GM-L motherboard
	(integrated GF4 with 8mb shared RAM, nForce2 lan and audio)
2x PVR-250


software:
Jarod's recommended nvidia nForce2 and gForce drivers
ATrpms kernel 2174 (the one recommended by Axel on this list a couple days ago)
myth 0.14
lirc
extra audio buffing enabled
jitter reduction enabled
de-interlace disabled (atm)
using VGA out to a SONY monitor
GF4 TV-out enabled but not tested yet

I followed Jarod's guide with only one hitch which was the thing he suggested must be done for the install to go off without a hitch. I forgot to comment out the KDE-redhat lines so mythtv-suite did not install and I went on and installed the PVR drivers and realized the mistake when mplayer was not found. I then installed mythtv correctly and continued. Don't know if the order is important.

The only other quirk is when upgraded the kernel, I had to rpm -e {nforce drivers} in order to install the rebuilt ones and from then on out I would get a warning on certain apt-get processes complaining about something powerk7.so (don't remember the exact warning and I'm at work right now, shhhh). 

Other than this hang, the system is operating flawlessly.

>From the nature of the problem it seems to act like an array indexing problem but since the system hangs I get no error message. I'm not sure where to check for this error in a log either.

Please give me a hint where to start tracking this problem down.

Thanks much for the support!
