Hi,
i got a
TerraTec Cinergy DT USB XS Diversity
http://www.linuxtv.org/wiki/index.php/TerraTec_Cinergy_DT_USB_XS_Diversity
Running well with v4l (except the problems with the SB700 USB ports of
my MB (disconnects here and then) => I am using a PCI USB Card with NEC
Chipset and everything works well).
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.
