Kaffeine doesn't work with MFE tuners (at least not the version I have). It only sees one delivery system. If you're using the very latest version of the driver (the one at the media-build tree), you can use the dvb-fe-util tool to change the delivery system to DVB-C or to DVB-T. The tool is now part of the v4l-utils. You may also request a Kaffeine developer or to submit a patch for it, in order to add support on it to detect the frontend supported delivery systems and to change it dynamically. > > Regards, Mike. > > On Tue, Jan 10, 2012 at 4:42 PM, Fredrik Lingvall > <fredrik.lingvall@xxxxxxxxx> wrote: >> On 12/25/11 16:56, Fredrik Lingvall wrote: >>> >>> On 12/18/11 10:20, Fredrik Lingvall wrote: >>>> >>>> On 12/17/11 20:53, Mihai Dobrescu wrote: >>>>> >>>>> >>>>> >>>>> >>>>> Mihai, >>>>> >>>>> I got some success.
