One thing that bugs me: The recording/reception quality is much worse that with windows. Using the Terratec Software i get 100% signal and 100% quality in check-mode and i NEVER got any frameloss or other picture/sound errors. Using v4l and vdr i get mpeg-blocks here and then (5 minutes) and even soundloss or complete frame loss. Femon-Plugin for VDR shows me STR/SNR/BNR values which are in the lower orange area, really close to red. => BAD! What may be the cause? This is set: options dvb_usb_dib0700 force_lna_activation=1 Would be nice to see help to get 100% signal back.
