Hello,
I'm trying to get a Terratec S7 to work. The driver, just cloned
v4l-dvb, compiles and loads fine but when I try to scan Astra 19.2E only
a few stations get scanned. In most cases I get a tuning error. Under
Win7 the box works perfectly, so it's not a hardware defect or antenna
specific issue.
Any help would be very appreciated.
Information about my system:
- Core i5 661 running on Gigabyte board

Here some output from w_scan during scan. With scan-s2 it's the same, I
always get "tuning failed".
Thank you for any assistance in advance and best regards,
