long term issues IRQ?

[tangye]

I've had issues using PVRX2 and previously GBPVR and took a few days off work to finally get to the bottom of them. I had crashes, strange remote control behaviour, some parts of the menu not working and some strange artifacts.
I have reloaded win XP and installed all the other stuff .Net, drivers, etc and just keep getting the same sort of problems. I've reached the point where I've swapped out all of the hardware from another PC, tried different codecs and different versions of drivers, as I've had similar issues with different versions, I've now convinced myself that the problem lies with the fact that the tv tuner cards and graphics card all share the same IRQ.
Is there a way to re-allocate the graphics card IRQ? I've tried setting the PC to 'standard PC' from 'ACPI Compliant' but couldn't find a way to change the IRQ.
I'd really appreciate any input as I'm stuck,

thanks in advance,

Tangye

irq's in modern machines are shared, cuz there's a finite # of them and more devices than irqs. so they invented a way to have them share them without problems...
so the fact that they all share a single irq isn't a problem..everybody's does pretty much..

i would guess the problems you're having are related to video card/drivers...
that one is barely up to sd video much less hd,and the ones i've had were buggy as they could be...is it a onboard video type? or replaceable? not much to choose from but there are several decent ati cards for agp still but nvidia seems to have stopped making them..[AGP]
i would recommend upgrading it even if you get it working ok...

but it could be something failing like ram or overheating problems...problems with remote,menus,etc. seem more like total system glitches, pointing to overall system instability...
that video card also uses the main system ram so also points to memory related..
hard to tell without more info...

In your bios, You should have a choice for plugandplay os... no means let bios configure irq, which is actually defalut and preferred for most system.

Yes, means let Windows decide resources. sometimes, you then have control to change some resources.

I can't remember the order I did this stuff, but I think I removed tuner, set bios to yes started windows. Shutdown computer, inserted Tuner card, started windows, windows found new hardware (think I reused existing driver), checked resources, all good, shutdown computer (NOT restart - computer needs a cold shutdown each time) started bios, changed to no and then restarted into windows, all good still

thanks for the replies,
The graphics card is fine it's a 256Mb nvidia 6200 and produces great pictures most of the time, I've swapped it out with another nvidia card and get similar issues and I've tried different drivers.
I've swapped out all components including the remote and receiver so I'm still convinced it's IRQ related, unfortunately ACPI HAL takes precedence over the bios settings so even if you set it to non pnp XP ignores this, I do know you can set the HAL to 'standard PC' and reboot and the IRQ's get reallocated but the graphics card and tuners still get the same IRQ.
I will try as suggested and emove the tuner cards and reinstall them in a non ACPI HAL and see if I can get them to be assigned to a different IRQ, fingers crossed!

EDIT:

Without PVRX2 running I can play anything in VLC or WMP with no problems

The way pBS replied is how I thought for a very long time. And then I got a HVR-1600 and then I started having what seemed like IRQ conflicts. So I went against my better judgement and played with the bios setting. I have acpi and never changed that. I was able to see manually changeable resources when the bios setting was set to Yes (allow Windows to control)

try overlay for your renderer if you get less crashes then its either video driver or video card related
gbpvr uses direct3d so if your card is borderline then artifacts etc may show and also cause it to crash the pc if the drivers are bad
if its just pvrx2 locking up then its normally more codecs i have found

i had a 6800 and it slowly got worse more and more crashes
so i replaced my systemboard(went dualcore cheap) and video card to a 8600nvidia
hasnt crashed since (8months)

I read this as meaning that you only have crashes during playback of a video? is this correct?

and that you also had exactly this problem when you swapped the card for another nvidia card? (so said "similar" so I thought it might be good to be clear on this point)

If this were the case, then you could remove the tuners and test just playback.

And also change render as suggested.
