Hello list, I'm having problems getting my Avermedia 771 DVB-T card working. I was hoping that someone on this list might be able to help me. Looking at dmesg I get the following: bttv: driver version 0.9.15 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0).
