I have had similar issues, but I had not made any correlations and had
no clue what was happening. Since my system hangs so often, I reboot a
lot (motherboard and/or video problems, not sure, but that's another
thread) and only miss recordings once in a while, probably when the
system has been lucky enough to run for a few days. You have described
my problem very well. Thanks for the work-around (reboot). I just need
to remember to reboot when there's something scheduled I care about
catching.
Have you tried messing with the capture card settings? There's an
"Analog Options" button/screen that lets you set the /dev/videoX device
that corresponds to the analog portion of your dvb card. I have two dvb
cards; a pcHDTV-3000 and a DVICO gold. Both have an analog section and
both are very similar (same chips?). I found that both had the
/dev/video0 defined as the analog device that is associated with the dvb
device (default, I assume). For me, the pcHDTV-3000 was wrong. I
changed it to /dev/video1 as /dev/video0 is the analog portion of my DVICO.
Also, do you use the analog section with another program (tvtime
maybe)? I do, and I'll see if using that screws up Myth's ability to
use the dvb portion of the card. I've changed that /dev/video, now, so
maybe no more missed HD shows. Hopefully......
