I ran KnoppMyth-tz and set my time zone to Central (which it already was), but my schedule it still off by 2 hours. I re-ran mythfilldatabase, but that didn't change anything either. What else affects the time in the XML data?

rerun mythtv-setup and make sure you don't have a time offset for xmltv.

Still crashing. This is my entire log output from /var/log/mythtv/mythbackend.log. I love the program when it is running, but so far the longest recording I have done is 43 minutes.

Your crash problem is most likely due to the via chipset, and I'm sorry, but there is no other workaround than different hardware. you'll either have to replace the mb or replace the pvr with a software card.

It's now running on an nvidia chipset. It's an A7N8X-deluxe mb. I've read of easy success stories with almost the exact same set up I have.

A7N8X-deluxe
512 MB Crucial RAM
PVR-350

Is there another log that can actualy give me some info as to what is causing the freezing?

Thanks,
--Ryan

/var/log/messages would be the best place to look, but it doesn't always show anything if the crash is bad enough. Unfortunately now you may be suffering from the nforce2 apic problem. This one does have a solution by recompiling the kernel, or waiting till R4v3 is released sometime soon and it will have a fix in place.

how do I set it to rebuild the kernel to fix the apic problem? I was also thinking it my be the hard drive, so I was going to reinstall in on my 120gb hd. These are the last errors I got in the backend log:

IOBOUND - blocking in ThreadedFileWriter::Write()
IOBOUND - blocking in ThreadedFileWriter::Write()
IOBOUND - blocking in ThreadedFileWriter::Write()

Anyways, what is the apic kernel command I need?

Thanks,

It's not just a command it is recompiling the kernel with the local apic option turned off and is not for the faint of heart or linux newbie. If you don't already know how to recompile a kernel I would suggest waiting for R4v3.

Well, I'm definitely not a linux newbie. I worked a few years in network administration. Done plenty of kernel rebuilds, just a newbie to the whole video capture side of things. I guess I'll probably be waiting unless my reinstall on the new hd doesn't work. If it keeps failing I'll probably have to investigate the apic problem.

Thanks for the info.

Sorry didn't mean to insult you it's just that it is rather difficult to walk someone who's never done that kind of stuff through it cause as soon as you recompile without local apic you break lirc and ivtv and a couple of other things that also have to be recompiled at that point.

A couple questions about APIC. I read in another post that someone ran the install with "noapic" as the boot option and it worked for them. I looked at the boot options and that wasn't listed. Does that really work? Second, when will R4V3 be coming out? I'm looking into the kernel problems with apic and just wondering if it's worth my time to figure out.

Finally a non-apic related question. Why will my computer not boot if I don't have my hard drive and cd-rom drive on the same ide channel? I had it configured for a drive on each ide channel when I had Windows installed on it, but when I boot knoppmyth it says Invalid System Disk. Just wondering because having the hard drive and cd-rom on the same channel really makes the ata-133 hard drive pointless.

Thanks,
--Ryan

not sure about the same ide channel thing. shouldn't matter my box has the hard drive and dvd drive on different channels. the only real hard rule right now is that the harddrive has to be primary master, but the dvd should work just fine as secondary master.

As for the APIC issue some motherboards require you to boot, or install with the noapic option. This is a different issue than the freezes caused by the nforce2 mb with pvr250's. The issue with the freezes is "local APIC" It cannot be turned off with a boot switch in kernel 2.4. For kernel 2.4 to fix this issue you MUST recompile the kernel after running the config and removing the "local APIC". In the 2.6 kernels there is a boot option that you can put in lilo/grub or any other boot method "nolapic" and yes the l is supposed to be there it's not a typo.

Since knoppix is debian based would an apt-get of the 2.6 kernel fix my problem or would it create more problems with other modules?

well first you would have to change your boot loader for the nolapic option but it would fix the problem. However it would break ivtv (the drivers for the pvr cards) and lirc (remote drivers) and maybe others.
