Hi, I have a Twinhan 102G DVB-s that is not tuning. Building the stock 2.6.14 kernel drivers: Linux version 2.6.14 (gcc version 4.0.3 20051111 (prerelease) (Debian 4.0.2-4)) #17 SMP Mon Nov 28 13:33:56 PST 2005 loading modules with: options bttv i2c_hw=1 card=0x71 i2c_debug=1 options dst verbose=4 setting freq with szap produces a great deal of output that LOOKS (to me) like i2c communication is working up until: Nov 24 21:43:33 skookum kernel: dst_comm_init: Initializing DST.

I have since tried rebuilding with the new merged v4l-dvb tree, well it was in the intermediate "make merge" phase, the problem still seems to be the same, although the debug output is less. (fewer retries) So is it timing problem? or something else? or something I have just plain done wrong. I have also tried setting dst_addons=0, no luck Is the dst_ca modules supposed to load? Thanks, mark
