Sundtek MediaTV Pro (Europe) / Low signal quality
« am: Dezember 23, 2009, 11:03:41 Nachmittag »
The new driver does not crash my mediasrv anymore 
But I have a problem with my signal quality. The 2 DVB-C PCI cards I'm using are giving perfect streams. But when I try to capture from the dvb input, I get a very distored screen. I've disconnected the other cards and using the same input cables as for those cards, so the quality of the line signal must be OK. Czap reports:
status 1b | signal ffdc | snr 0000 | ber 00007fa9 | unc 0308cf08 | FE_HAS_LOCK
when I'm using lower signal quality cables, the signal ffdc lowers to e000 or b000, but in all cases the ber is still above 0.

See the attached screenshow of the best quality I can get..
Any ideas how to improve the quality?
