Hello,

I am trying to get my card to work on linux. The problem I seem to be having is that it will not accept my frequency rate or my symbo rate.

The Frequency rate I am trying to scan is from 267000000 - 699000000
The symbol rate I need to scan is 6952000

These do work in windows so I know the card suports these values and it must be the driver that is not allowing the values in linux.

Can you help point me in the right direction on how I can go about changing the driver to allow these values.

Thanks

Mark

The driver was originally submitted with a maximum symbol rate of 6900000 in the DVB-C frontend, and the value is still there. I for one don't know why that is and if there is any deeper meaning to it or any hard limit that we must not exceed...

If you have the source of the presently installed kernel, edit drivers/media/dvb/firewire/firedtv-fe.c, run make modules and sudo make modules_install, unload and reload the driver, and see what happens.

PS: Whether you succeed or not, either way please leave a note about your results here or send a message to linux-media@vger.kernel.org.
