Andy, Thank you for this patch! I'll add it to the ivtv-0.4 tuner module myself, but to get this patch into the kernel I recommend that you post it to the [email protected] mailinglist (see http://www.linuxtv.org/v4lwiki/index.php/Main_Page). You also need to add a 'Signed-off-by' line (see http://www.linuxtv.org/v4lwiki/index.php/SubmittingPatches). One suggestion: in the tuner_lg_ntsc_tape_params struct you should only put the '= 1' fields and omit the '= 0' fields as that is always the default. And the amount of comments is a bit over the top :-) Remember that most tuners are identical, except for bandwidth ranges and the bandswitch bytes. So only special, non-standard properties need to be documented.
