[linux-dvb] Problems with frontend frequency selection TDA chip

["Malcolm Smith" <Malcolm.Smith@itemplus.com>]

Hi

I'm running the latest stable version of dvb drivers (linuxtv-dvb-1.0.1) on
a Nova-T DVBt pci card in the UK. I'm on the winterhill transmitter which
has frequencies

channels 56, 66, 60, 63, 67, 68 - which translate to a frequency range of

754,166,670 hz through to 850,166,670 hz.

The card works fine in Windows Xp and can receive all channels, it struggles
however in linux.

I've used the dvbtune program, compiled with the current driver.

The card can tune up to 824 Mhz but then gives "invalid arguement" on the
IOCTL

Help please.

I've run the program below 3 times... one with a valid MUX
one with 824 Mhz (no signal, but it can select the frequencey)
one with 825 Mhz (Invalid arguement)
