Steve, To ensure MPC-718 DVB-T support can be included in the Linux kernel, I have checked in changes to my MPC-718 development repo to: 1. extract a "firmware" sequence from the MPC-718 Windows driver 2. load that firmware in the cx18 driver to help init the MT352 on the MPC-718 See http://linuxtv.org/hg/~awalls/cx18-mpc718 Please test it when you can 1. Run the get_dvb_firmware script with my changes from that repo and install the new firmware file: $ cd cx18-mpc718 $ chmod u+x linux/Documentation/dvb/get_dvb_firmware $ linux/Documentation/dvb/get_dvb_firmware mpc718 $ sudo cp dvb-cx18-mpc718-mt352.fw /lib/firmware (or wherever for your distro) 2. Compile, install, and test the updated cx18 driver from that repo. Once we know it works for you, I can build a cleaned up patch set and ask for it to be pulled to the main v4l-dvb repo. I'd still like to fix (and have you test) the EEPROM dump after we know the DVB-T changes are good.
