Hi,

If I leave Myth running for extended periods, everything is fine until I try to watch TV. I get nothing. MythWeather works. If I leave it on Live TV, the image will freeze. I can usually kill mythfrontend and everything comes back. Last time, this wasn't enough. I had to resart the computer. I was able to swtich to another console and reboot.

Should I upgrade MPlayer or spend time getting the TV out to work on PVR350? Does TV out still use MPLayer? When I tried to do an apt-get upgrade of mplayer, I received an error about virtual package. Any ideas ?

Best Regards,

Paul

Hi,

I tried to install the 586 version as I have a PIII-800 and thought that might be the problem. Had another lockup while watching live TV. Used MythWeb to record rest of show. Waited until show was over.

Killed frontend. Console at F7 wouldn't come back. I entered KnoppMyth-run from console at F1. It started back up. I then was able to watch rest of show. Backend must be fine during dislplay lockups. Any ideas welcome!

TV out and MPlayer have nothing to do with one another. I'd suggested using the source for MPlayer that is provided and recompile that. Give me a day or two and I'll have instructions on installing the latest ivtv drivers. Those w/ 350 may have better lucky w/ the newer driver and TV out. You probably also want to go back to i686...

Sounds great! Thanks. I went back to 686. Can you point me to the mplayer source files? I can't seem to locate them...

I use a 350 as well and am on the i686 version (on an AMD Barton CPU), and am having serious freezes as well.

It started as a slow memory leak. Within 20 minutes my 512 would be empty. I searched the various myth newsgroups and a lot of people had the same issue. I tried the various recommendations and managed to get my freeze down to less than a minute.... that in the wrong direction. The only thing that seemed consistent amongst people was to turn off APIC in the kernel. The BIOS makes no differenece, nor does command options from lilo to the kernel. I believe you need a 2.6 kernel to turn off the APIC (and LAPIC).

If I have anytime this week to try and get us a new kenel I will, but if anyone has a chance, please POST!!!

Is there anyone out there with APIC on (dmesg| grep -i APIC) and having fine TV? I cannot even record anymore...

ivtv: init error 20. Code -16

ivtv: timeout waiting for data
ivtv: timeout waiting for data
ivtv: timeout waiting for data

Sorry for the brief post... I was trying to get it all in before it scrolled off the screen. In my case, it looks like a definite ivtv problem. When I switch to live tv, these errors all popped up in F1.

When I start Knoppmyth-run, I get:
ivtv: ivtv-api.c: unknowm ioctl 0x80585600
ivtv: ivtv-api.c: unknowm ioctl 0x 803c7601
ivtv: ivtv-api.c: unknowm ioctl 0x 80585600
ivtv: ivtv-api.c: unknowm ioctl 0x c0405602
ivtv: ivtv-api.c: unknowm ioctl 0x c0cc5615
and about 15

ivtv: qctrl: invalid control

memory is has over 256 MB free. Continues to say no data available then gives error messages. They scroll by. I will be happy to cut and paste from syslog if there is any interest.

I have APIC enabled on an nforce2 motherboard chaintek 7nif2 with a pvr250 sorry I can't afford the 350.



as you can see that was friday which was the last time it was rebooted. The only reason it was rebooted then is because we've been having some power problems and I haven't gotten a UPS for that box yet.

Xsecrets, is your 250 working fine with TV? No freezes?

I get those ivtv timeout errors after every other boot. Very wierd. It could be because maybe the boot failing is coming up after a freeze. Even when I don't get the errors, I cannot watch live TV though.

I hope one of theo boards posts a fix to this soon. Big PITA

nope no freezes at all everything works fine, well at least everything I use. livetv, recording two channels at once, dvd rip and watch, music rip and play, weather, news. I think that's all I use. I don't use mythgame. I used to have kernel oops every once in a while, but after my last reinstall everything works great. onlything that makes the box go down is power outage.

I also have been experienceing freezes with my MythTv box w/ a PVR250

I was running it in a one of those SHuttle SFF cases w/ nforce2 board.

From trolling other sites all i've come up with is someone else who also had the same issue and (knowing more about linux than i do) narrowed it down to the nVidia sound drivers.

Right now i'm trying to put together a spare box to see if i can solve the problem with a new MB+Soundcard+PV250

(I can't slap a new Soundcard into the SFF, there is only 1 PCI slot .....)

well if you are using knoppmyth with a nvidia motherboard you won't actually be using the nvidia sound drivers. Knoppmyth uses the intel8x0 alsa drivers for the sound.

To rule out MPlayer, I did the following:

apt-get update (wait a while)
apt-get install mplayer-386
reboot

Everything worked fine for almost 18 hours. Then live tv locked up. Turns out the backend is still fully operational and recording shows. All I need to do kill frontend and restart it and everything is fine. No lost recordings. I did see a message that there were no free buffers and memory was 510MB used out of 512MB. After killing mythfrontend and restarting it, it was about the same but everything works fine...

I'm kind of at a loss. I have heard their is a known problem with acpi. Are there other known problem which could lead to this?

I've the same delayed lockup problems (backend still working) with a WinTV-GO, Athlon2100+, SB-Live on a ECS SIS735 motherboard.
