v4l-dvb-20070818 patched for multiple simultaenous frontends.
I tried to use the stoth drivers but i could only access the DVB-T port on
those, the DVB-S port wasn't available.
I'm using mythdora-4.0 with kernel 184.108.40.206-61.fc6

some channels, but not all.
Maybe I should try again with the stoth drivers...
Thanks for responding..
