[mythtv-users] mythtranscode results in 15GB files

Seems that I can only restart Myth backend a couple of times before it
causes the drivers for my Leadtek capture card to crap themselves.  

After this I get segfault if I execute anything (think "ls" or "reboot"
from an existing SSH session)... This is a hard reset and all is ok

It doesn't seem to affect the DVB-T card that I have - my guess is that
it is just streaming the input from that card to disk where the analogue
card has to frame capture.

I intend to replace the Leadtek card with a PVR-250 or a DVB card that
has hardware MPEG-2.

However a PVR-250 is about $400 Australian - I make ok money writing
software, but for a "Cheap" PVR this project is starting to add up.

What exactly makes your myth box need rebooting? mythtranscode does
nothing exotic, but it almost looks like long running CPU hogs seem to
cause mysql to clog, or to get f&cked somehow...

I've written a script to detect some of the symptoms of that and take
appropriate action (restarting mysql and mythbackend), and other than
issues with mythtranscode and large files (which I've also written
monitors and workarounds for) I am usually perfectly stable (minus
frontend crashes) until upgrade time. Let me know if you'd like those
perl scripts.
