Hello, it seems like the cx24110 frontend somehow got unsupported during frontend refactoring and, hence, does not work anymore with dvb from kernel 2.6.10 (as far as I checked this also holds true for cvs). Please find enclosed a preliminary patch. It works for me but might need some more work. If anyone dares to try it out, I'd like to hear about the results, please...
