Hi,
I am trying to create a stable system with mythTV. I have limited my
problem down to my PVR-150MCE card. For some reason when I record TV it
freezes the entire system requiring me to hard reboot to recover. This is a
huge problem for a Myth Server!
Some info on my server:
Fedora Core 6
P4 3.4Ghz
512mb RAM
Nvidia 6200 (binary drivers installed)
HDHomeRun
Firewire
PVR-150MCE

I have disabled all my PVR-150 schedules and when i record only from the
firewire or HDHomeRun the system never locks up. But when recording through
the PVR i get about 5-60mins before the system freezes. I started with
installing mythtv with Jarods Fedora guide. Since the initial install I
have compiled Mythtv SVN and compiled my own IVTV stable drivers from source
instead of using RPM's.
a cat of my /var/log/messages reveals...

This line grabbed my attention...
Aug 7 23:16:36 mythtv kernel: ivtv0: All encoder MPEG stream buffers are
full. Dropping data.
Aug 7 23:16:36 mythtv kernel: ivtv0: Cause: the application is not reading

but how do i fix that?
I hope I have provided enough information as to the system/issue. Please
email if you need more info or have a fix! Ill be quick to respond.
Thanks,
Mitchell
