Hello all
Im using gentoo amd64 kernel-2.6.13 with a Hauppauge DVB-s Nova CI with
vlc-0.8.2. The first time I start vlc for dvb-s streaming, I get this
message (in dmesg). vlc is working, as long as the stream is
unencrypted. Encrypted streams dont work, because the ca0 device crash.
dvb_ca adapter 0: DVB CAM detected and initialised successfully

This looks very bad to me! the /dev/dvb/adapter0/ca0 is locked now, even
if I terminate vlc.
It's even unpossible to rmmod the budget-ci module.
any hints?
I also get a lot of other messages in dmesg that are related to vlc. I
restart vlc now every hour by a cronjob, else I run into out of memory.
after 2 hours, vlc is consuming about 2-3gb of memory.
