Hi, Sorry for cross-posting this to both the development and users list. I am at wits end with my Myth setup. I haven't enjoyed the reliability of MythTV/ivtv like some other people are experiencing. For the longest time, I thought it might be a problem with Myth itself. I posted my problems to the Myth mailing list, but nobody could help me with them. However, after adding some more heavy duty debugging to my ivtv module, it appears as though this is the culprit.
Basically, I have two problems that I've been experiencing. Although, I believe both problems are related, if not the same. My first problem is that, when I watch live TV, the system will freeze up and the show I'm watching will go into a loop like a broken record. (ie. the last few frames recorded will keep repeating over and over). I can't do anything except a hard reboot (even ctrl-alt-del doesn't work) to get the system back to a usable state - I can't get to a terminal window, nor can I telnet/ssh into the box. The next problem, which is the one I have included the log entries for, is where Myth will chug along happily recording the show, then all of a sudden it'll throw some error messages into the logs, and stop recording. I have a process that watches the logfile for the words "ENC: User stopped capture" (which I actually did not stop the capture) and restarts my Myth backend. After this happens, there's no way of loading the Myth frontend to watch live TV. I've tried reloading the firmware but it doesn't work (logs attached for reloading firmware). The only way to get my system back is a complete system reboot to force everything to reinitialize. I've tried two separate versions of the Linux kernel, as well as two separate versions of the ivtv driverand several versions of the Hauppauge PVR-250 firmware. In every case, the results are the same. My hardware configuration is as follows: - AMD Athlon XP 3200+ - Asus A7V880 motherboard (onboard sound, network, S-ATA controller) - 1 GB RAM - 1 x 120 GB Western Digital ATA drive (for the operating system) - 2 x 120 GB Western Digital S-ATA drives striped together (for the recorded programs) - Hauppauge PVR-250 My current software configuration is: - Debian unstable - MythTV 0.16 - built from Debian source packages - Custom kernel 2.6.10 (also tried with 2.4.27) - ivtv 0.2.0-rc3c (also tried with 0.1.9) - firmware pvr_1.18.21.22301_inf.zip (I've also tried pvr250_17_21288.exe, pvr48wdm_1.7.21337.exe, pvr48wdm_1.8.22037.exe, and pvr_1.18.21.22168_inf.zip) The following are the relevant log entries for my configuration and problem. Here's the ivtv initialization at startup...

It's been running unstable for a good 4 months now (probably even longer) and I've even been considering scrapping the whole Linux PVR and moving over to a Windows based system (GASP! Yes, I know. But that's how frustrated I am!). You folks are my last hope (no pressure...) to try and resolve this PVR instability I've been having. Any help would be greatly appreciated. Let me know if you need any more details.
