Subject: Terratec S7: Scanning doesn't reliably work on Astra 19.2E
Date: Mon, 19 Apr 2010 19:38:13 +0200 [thread overview]
Message-ID: <4BCC9505.1000801@tinderbox-art.com> (raw)
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

Thank you for any assistance in advance and best regards,
