I've fixed the problem with my tuners, ....... (my mythtv SQL database simply {ahem....} needed to be repaired).
.....so now back to the plot.......
I've extracted the .fw as mentioned previously and copied it to /lib/firmware
I've loaded/compiled/installed the "repo".
I've re-tuned both cards and I can report that everything seems to work again. Cards are recognised,
there are no error messages (that I can see) in dmesg or /var/log/messages.
Summary : I can watch DVB-T on the ACER Idea 500 using your last repo
Is there any other verification that I need to do ? (EEPROM notwithstanding, which I know you still want me to do)
I've included "grep mt3" sections of messages and dmesg below. If you prefer the full files I can send them
under seperate cover. I tried "grep-ing" for cx18 but the filesize was above the limit

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
