xawtv and kwintv segfault with the new drivers
Hi,
I use both a hauppauge bttv and a dvb on a pc (no tv) with a loopback video
cable from the dvb to the bttv external video input. Used to work real fne.
Well, I switched to Mandrake 7.2 and the latest VDR abd DVB drivers (kernel
2.2.17-21 recompiled, fresh install) and am having trouble getting the tv
apps to work (and besides not getting VDR to respond to LIRC).
The first time they are run, it appears both xawtv and kwintv segfault, the
following attempts give a "device already occupied" message. (nb: tested
isolatedly with only analog drivers, xawtv and kwintv do work in my system)
------------
kwintv:

Strange because with the same config and load order this worked real nice
before with the very same modules.conf
I am loading the drivers with:
make insmod
/sbin/modprobe bttv card=10 radio=1 pll=1
then I load the lirc (I am using the hauppauge infrared command)
and finally vdr.
everything appears to be loading correctly:
