[linux-dvb] dvb technotrend budget won't work, please help me!

[Benjamin Adler <benadler@gmx.net>]

Hello!

I bought a Technotrend DVB-C PCI budget card on eBay 
(http://cgi.ebay.de/ws/ebayISAPI.dll?ViewItem&item=5100217074) and have now 
tried for more than two weeks to make it work with linux. I have really tried 
many different things, two different computers, many many kernel versions, 
looking for tutorials or asking people on irc for help. Noone could help me.

The dvb-c-card has a Philips SAA 7146A H chip, a Vista VES 1820 chip and the 
tuner is labeled "TDBE2-032A 082113A". The card works fine in windows XP. I 
have built the corresponding options into my gentoo-patched-2.6.7 kernel. 
Compiling as modules doesn't make a difference. After booting, dmesg tells 
me:

Linux video capture interface: v1.00
SAA5246A driver (SAA5246A interface) for VideoText version 1.6
SAA5249 driver (SAA5249 interface) for VideoText version 1.7

Zoran MJPEG board driver version 0.9.5
No known MJPEG cards found.

proper sysfs support, see http://lwn.net/Articles/36850/

But when I execute the scan-utility 
in /usr/src/linuxtv-dvb-apps-1.1.0/util/scan/ with "./scan dvb-c/de-wtnet", I 
get:

scanning dvb-c/de-wtnet

WARNING: >>> tuning failed!!!

Done.

I have created the de-wtnet file for my local cable provider (wilhelm tel in 
norderstedt, next to hamburg, www.wtnet.de) and it looks like this:

# Kabel iesy
# freq sr fec mod
C 450000000 6875000 NONE QAM64

The result is the same with other provider-files, though. Where is the 
problem, what can I try to fix this?

Thank you for your time!
