Hi all,

I'm having some issues with my setup at the moment, here's the rig: -

AMD Athlon 1Ghz
640MB Ram
Nvidia 3D Profit 256K (with svideo out)
8GB Segate HDD (for development environment)
PVR-250 model 983
(PAL UK setup)

I found that the PVR-250 card had a type 18 tuner in it.

I have had lots of stability issues with the backend server crashing on me.
Firstley I had the PVR card type set to 83 (as it couldn't be auto-detected), and the
backend would crash regardless if i was watching live tv or recording for longer than
30sec.

I then set the card type to 85 and was able to record for 2h's without issue, but
while watching live tv the backend would crash after 3min (better than before).

I also have issues playing getting the program guides and playing dvd's but i'll post about
those once i get the system stable!

Is this a config of the card or ivtv that is causing the crash??
here is an extract of /var/log/mythtv/mythbackend.log

Code:
Starting up as the master server.
QSettings::sync: filename is null/empty

TIA

ok I have done a reinstall on a 40GB seagate drive
compiled the ivtv-0.1.10...... drivers located in /usr/local/lib
installed the nvidia drivers via install-nvidia.sh
modified /etc/mythtv/modules/ivtv for the tuner type 18
added options ivtv card=84 type=18

i have made some recordings of over an hour however live tv will not last longer than 15 min
before the backend crashes.

any idas where i should be looking to track this down??

TIA
Steve

You wouldn't by chance have a Via chipset on your motherboard would you?

yes it's a QDI KinetiZ 7T board
Datasheet http://www.qdigrp.com/qdisite/eng/products/K7T.htm

north bridge:VIA KT-133
South bridge:VIA VT82C686A

by you question i pesume that this is an issue! :shock:

And if so is the resolution a software or hardware change?

If it's a hardware change i might have to reconsider my final system setup.
i was going to go down the road of and EPIA M10000????

search the forums for more info, but there is a known dma bug in the via 133/266 chipsets, and it shows itself with the pvr250 cards. There is no proven solution other than changing motherboard.

You might want to do some research before you jump down the road of the epia as well. They have their own issues, however they are all correctable with some work.

Don't count on replacing your motherboard to cure the problem. I replaced my via motherboard with the recommended nvidia board and still have similar problems. I found that replacing the OSD with isthmus helped more than replacing the motherboard, so you may want to try that first. For more info see this thread:
