Can't reproduce error with my SAA7134 based PCI card (LifeView
FLYTV3000), gcc 4.2.1 and glibc-2.6.1.
I used valgrind and didn't see there anything strange except several
memory leaks.

Hope you run "make distclean" before "make" after changing configure
options (missing this 90% leads to intermittent SEGFAULT).

Please help to isolate bug:
0. Enable full debug output (-msglevel all=9)
1. Try v4lv1 driver (driver=v4l)
2. Try another video/audio codec
3. Try to use OSS driver instead of ALSA if it is possible
4. Try -nosound

P.S. If anybody else has similar analog card (do not know what chip it
uses, there is no such info in original report, though),
please, try to reproduce bug.
