I cannot get my DVB-C card to even find a signal using the Linux driver.
Works fine under Windows (reference software 2.08), so all parameters should
be correct. Watch TV Pro works too. It uses the same driver as the reference
software. WinDVBLive DOES NOT work. Seems to be the same problem as with
Linux.

* Technotrend DVB-C v2.1 with optional CA-slot (but no CAM).
* RedHat 7.1 w/ Linux kernel 2.4.16
* Latest DVB-driver package (2001-12-12) from convergence.

Can someone please tell me ANYONE have a rev "C-2.1" that works!!!

Does the driver developers have this card available for testing? It is
supported according to the list @ http://www.linuxtv.org/developer/dvb.xml

Can the driver developers please comment? Am I doing something wrong? What
can I provide you to further comment on this?

Regards,

Stefan Norberg
