It seems I have the same problem.
Myth 0.14 was working  fine, and now it is crashing about once a day,
normally at the begining of the day.
My setup is:
System: Debian Unstable
Card: Winfast TV200XP Deluxe
Location: USA

Unfortuantely there is no way back to 0.14 because of grabber issues...

Since at least 2 users reported problem on Debian , could it be that the
Debian package is broken?
Did somebody try to build from sources?
