[linux-dvb] difficulty getting Nova-T working with dvbtune

[gryn@riffraff.plig.net (Glyn Davies)]

Hi there folks,

I've been lurking around for a while, and finally got around to getting a Nova-T card.

As expected under Windows the picture is great, but the software is terrible so I am now
trying to get the card working under Linux.

I have downloaded the driver (from Henning Holtschneider's web site - thanks btw) and compiled up.

Everything seems to work, I've traced the tuner being detected, etc.  However when I attempt to tune
I get:

tuning DVB-T to 505833000
Getting frontend event
Received failure event

On startup (installing the modules) it seems the module attempts to tune to a frequency:

Jun 30 11:35:18 tv kernel: tuner: tv freq set to 730000000      // Repeated a number of times
Jun 30 11:35:18 tv kernel: buffer == 0x11 0xf4 0x88 0x00        // 

Which is hardcoded into the module.  I've changed those to make it attempt to tune to my local transmitter
(crystal palace) and had similar results.

Adding some debug into the module when the 'failure event' is set appears that the initial tuning being done
by the module causes this to happen - ie before I've ever asked it to tune to anything.

Anyone got any clues here, as I can't see what I'm doing wrong...

Cheers,

Glyn
