Hi all. First of all I'd like to thank you for all your efforts. I am a happy twinhan user :) , I had reported earlier that my card didn't work on linux. I am now using it perfectly with 2.6.12-rc6-mm1 I figured out all the stuff about scan and szap and mplayer. I can scan transponders with vertical polarization, and watch channels on them that have vertical polarization perfectly. But horizontal scans fail and even if I write channel information manually szap or mplayer fail to tune. also my dmesg is filled up with messages like this : write_dst: _write_dst error (err == -5, len == 0x08, b0 == 0x00) dst_error_recovery: Trying to return from previous errors... write_dst: _write_dst error (err == -5, len == 0x08, b0 == 0x05) dst_error_recovery: Trying to return from previous errors... Thanks in advance for all the help.
