[linux-dvb] tuning problem on Skystar 1

[Honza Petrous <hop@unibase.cz>]

Hi,

I have Technostar's Skystar 1 PCI card, rev. 1.6.
The drivers was successfuly installed:

But trying to tune the card ends with errors:

# dvbtune  -f 12977000 -p v -s 27500 -t 0 -D 4

SEC VOLTAGE:  13  (2)
SEC CONT TONE: OFF

Not able to lock to the signal on the given frequency

The same problem has VDR, so I guess that there should be
problem with drivers. 

Somewhere on the list I saw (when tried to find answer for my
problems) that some code is downloaded to the card during
driver initialization. I found some code for it in the
drivers's dvb.c file. But I don't understand it. Is it needed
or no?

With regards.
