Hi all,
I am having some problems getting some channels to work on usb dvb-s
devices.
tried 2 so far a skystar and teviis660 both have the same problem.
I am about to switch from an PCI-e card to a usb hosted solution. My
PCI-e setup (skystar too) never had any problems.
both systems on a 4.9 Kernel. Astra 19,2
Problem on the USB system
using dvb-utils scan, It doesnt find any HD channels. the only one is
WDR HD which seems to be the only one using QPSK. the other are 8PSK I
think.
using mythbackend, I am able to scan and find the channels, but when
its recording, the quality is poor with a lot of errors in the picture.
nothing in dmesg, but if I do a "scan -c" using dvb-utils after
mythbackend locked one of the channels I get
