random computer lockup in live tv mode

[davde]

Hi all, been lurking around for a coupla months, solved most of my probs so far just through reading wealth of info here and at wiki. Great software and community both. I've had more fun testing , tweaking, adding pluggins etc, than i have playing video games lol.
My issue is im getting a random lockup (hard crash) of computer while using live tv...may also have happened during a recording or two in past month as they mysteriously "failed". Using 1.2.13, only pluggins installed are torrents , web cam, and comunity skin...all are working the way they should.
System specs are amd 3700+,asrock mobo socket 939, 2 gigs ram, ati 1950 pro vid card, 160 gig ide hd, hauppage pvr150 tuner
Happens very randomly , ive watched for hours without issue, also had it happen twice in last 2 days. Never have seen it using hauppage software, but since finding your program, i hardly ever start wintv.
I'll attach log files, thanks in advance for any help or suggestions you may be able to offer...cheers dav

If its locking your computer hard, then its most likely occurring in a driver somewhere (ati/hauppauge/mb chipset), but could also be caused by some other hardware instability(memory problems, or power supply etc). This type of problem cant really be caused in an app running in user space, so wont show anything in the GB-PVR logs.

hi, thanks for getting back so quick, hope i didn't wake you. I hear what you are saying and will investigate/update drivers, hardware, ps and ram etc.
Very odd as its an otherwise completely stable machine, has never crashed in any other app, runs 24/7 days on end...
I did notice in one of the logs i sent you that it was giving an error code..."2008-08-19 11:48:00.750 VERBOSE m_pD3DDev->Present() failed
Error code : 80004005
E_FAIL
An undetermined error occurred"
thanks again dav

This type of application could easily be exercising part of your system or drivers which arent used in your normal operations. (capture device drivers, videocard renderer support, videocard dxva support etc)

Even if I wanted to, I couldnt think of a way to make GB-PVR lock your machine hard - this type of problem can usually only occur in driver code.

This is normal, and can be safely ignored. It happens when yu shut the application down because the application tries to update the applications menu display one last time but the Direct3D support has already been shutdown.
