Hi Igor, I've taken some photos of the tuner so that hopefully you'll be able to help work out why it won't tune in Linux. Please see the following link for the images: http://www.flickr.com/photos/7690303@N04/sets/72157621703527801/ The only chip on display is: SDMC DM1105N D735 E280034 Also - I tested the card in a Windows box today, so I am now certain that both the card and the satellite connection are OK. The settings that work with Windows (frequency, etc), don't lock in Linux. (I do get a good signal reading in Kaffeine that is the same as Windows gives, but no lock.) I hope this will help you work out what is wrong. Thanks! Shaun 2009/7/22 Igor M.
