[mythtv-users] More crashing when watching live or recorded tv (Increase prebuffer?)

[wishbone at h4b.org]

Is there a way to increase the prebuffer for watching live tv?  By prebuffer I
mean the time it takes before it starts playing the ringbuffer?  I'm still
having difficulties with mythtv stopping while playing recorded or live tv.
Usually what happens is the backend will crash and the front end will just
lockup when that happens.  I get no errors on the backend, but the frontend
reports something about QTIME and Delaying to next trigger.  I even had my
system just reboot once.  I've read that people think it's ivtv's problem, but
so far:

mplayer with a 10meg cache will play all night long without problems directly
from /var/video
mythbackend records shows for me all day long without a problem.

The only problem I seem to be having is with using mythfrontend to watch
anything. I'm not sure if it's helpful but I've included the messages I get
with loading the modules.  If anyone need additional logs/debug to help please
let me know.  I'm so close to getting this to work!  My setup:

Dual intel 1ghz machine on an ABIT VP6 Motherboard
SCSI 10K Harddrive and adaptec scsi controller
1 gig of ram
PVR 250
GEFORCE 4 mx (used for tv out)
