It has everything to do with the tuning code in that Dnos104z NIM (incorrectly labeled, 'dee1601' in the kernel code) Chris Pascoe has found a way to fix this, but the fix has not yet been merged into the master branch. See here: http://linuxtv.org/hg/~pascoe/v4l-dvb-rounding If you want to find me on irc, I am there right now. I am in New York, -0500 ... #linuxtv on irc.freenode.net Here is a quick way to get things working for your device... Please follow these instructions verbatim: 1) hg clone http://linuxtv.org/hg/~mkrufky/cxusb 2) cd cxusb 3) hg export 56cb67d6c632 > FusionHDTVdual2.patch 4) cd .. 5) hg clone http://linuxtv.org/hg/~pascoe/v4l-dvb-rounding 6) cd v4l-dvb-rounding 7) hg import ../cxusb/FusionHDTVdual2.patch 8) make 9) sudo make install That should do it!
