Do you have a working linux driver in your kernel for your dvb-t card ? Do you have a sufficiently recent kernel with the proper modules configured or a sufficently recent v4l-dvb driver which have installed afterwards ?

my card is 3021 3091580-301
S/N 04082E01028
conexant Fusion 878A
25878-13, 0422Y1RN
0422 Taiwan
it's is the fisrt time i use Linux and DVB card, I use the modprobe: bttv, bt878, dst, dvb-core, dvb-bt8xx. I can tune the channels by the command:
% tzap - c channels.conf VTC1 -r
and watch it:
% mplayer /dev/dvb/adapter0/dvr0
but i can't play with VLC. i think i have installed card driver.
could you give me more direction?
