Live TV Reboot (crash)

[klyndt]

I just started on this whole endeavor, so please be patient.

I just bought a Media MVP, a Hauppauage WinTV 500MCE, USB-UIRT, and installed GBPVR (0.93.10). I run Windows XP Pro with SP2. I have an Athlon 2000+ running on a Giga-byte 7VRXP motherboard. This has a VIA KT333 and VIA 8233ACE north and south bridge.

The main reason for all of this was to be able to see time-shifted recordings on my TV using my home PC. Here is my problem: I can't watch live TV more than a few seconds over the MVP without my computer rebooting. When I try to watch TV on the PC I seem to be able to watch for as long as I want as long as I don't do anything. If I change a channel or do anything else, the computer reboots. I tried looking at various *.log files and I don't see anything, but I'm new to this. If you know of a file you would like to see let me know and I'll get it posted.

I can use the program that came with the 500MCE to watch TV and that doesn't cause my computer to reboot. Even when I change channels. I can use the GBPVR Tuning Assistant without any problems either. One other thing I have noticed is that after the computer reboots, most times the bios can't find the hard disks and just hangs on the boot screen. I have to physically power it down to get it to come up right. This leads me to believe that whatever causes the computer to reboot is either locking the hard drives or the south bridge. I have checked and I do have the latest drivers for the chipset.

I've tried looking throughout the forum for similar circumstances, but hardly anyone has a complete reboot just by turning on Live TV. Most posts I've read have to do with periods of functionality before something bad happens. So, I assume something in the live tv process is going catastrophically wrong.

Can anyone help?

If you're computer reboots, then you're having machine/driver/bios problems. This isnt a GB-PVR problem.

There are known issues with the combination of PVR500 and some VIA chipsets.

Where can I find a list of these "known issues?"

Also, I'm not convinced that it is a driver problem since I can watch live TV using other programs. Perhaps it is a dll that GBPVR is using and maybe it is different for the other programs I mentioned? Maybe then this dll has a bad reaction to the drivers? I have thought about that. What is the difference between the Tuning Assistant and the GBPVR Live TV? Are these two processes totally different, or do they share similar code?

Thanks,

I dont think there is a list as such, but I have seen various posts over the last few months. A few of these are:

Also, I'm not convinced that it is a driver problem since I can watch live TV using other programs.

You know, I cant actually think of a single thing I could do as a user mode programmer (ring3) to cause a machine to reboot even if I wanted to. Drivers running in the unprotected ring 0 have no problems doing this.

Your problem may be caused by the way I'm using the drivers, but if this was the case I'd surprised that no one else is reporting this problem. My main 'production' machine has a PVR500, and I've never seen a single reboot.

What is the difference between the Tuning Assistant and the GBPVR Live TV?

The tuning assistant uses the same code but does not access the onboard hardware MPEG encoder.
