Same here

What do these mean anyway? =-)

Identical error I'm getting

Not seeing these

Ditto

Ditto.

I am using ext3 for my OS partitions, and XFS for my data/video
partition, but lots of space free:
/dev/hda2             15116868   5364976   8983988  38% /
/dev/hda1               101086      7973     87894   9% /boot
/dev/hda5            139970152  63710408  76259744  46% /data

Anyone figure this out yet?  I'm guessing its an ivtv problem rather
than myth related, yet restarting mythbackend seems to fix the problem
(maybe it reinitializes the ivtv driver?) - maybe I should just cron a
restart everyday at 5am or something =)
