The original v4l-cx23418-* firmware files are still nedded.


To see if the new, additional dvb-cx18-mpc718-mt352.fw file is being
used, hmm....

On my kernel, the kernel would emit something like:

"firmware: requesting dvb-cx18-mpc718-mt352.fw"

at the "info" level in dmesg or /var/log/messages.


And following that, you *should not* see something like this in dmesg
or /var/log/messages being emitted by the cx18 driver:

"Unable to open firmware file dvb-cx18-mpc718-mt352.fw"

"Firmware dvb-cx18-mpc718-mt352.fw has a bad size: 100 bytes"

"The MPC718 board variant with the MT352 DVB-T demodualtor will not work 
without it"
"Run 'linux/Documentation/dvb/get_dvb_firmware mpc718' if you need the firmware"

"frontend initialization failed"

Andy
