Hi Pavol, Thanks. As said, I have not had any time to look into this, but will definitely do so. I own the same device, but do not have cable TV at home. Am using Conax CAM also successfully, so I believe that CI is not the issue. Some things that came to my mind still: Can you share the results of w_scan with very verbose output with both TT driver and the kernel driver? Also, make sure you use a recent version of w_scan - some distributions come with a rather old version... w_scan -v -v -v <your_options_here> 2>&1 | tee logfile.txt Also, if you want to try a later firmware for Si2168, have a look at this patch: http://git.linuxtv.org/cgit.cgi/media_tree.git/commit/?id=1b97dc98b58dad98f13fa0a4cdc819b60f3f3bff It is in media_tree already.
