Comment(by Boleslaw Ciesielski <bolek-mythtv at curl.com>):
Not sure how helpful this is but I am attaching a simple perl script to
generate the refresh rate mapping file as required by the patch. The
script uses xrandr and xvidtune to cycle through all available modes, so
it is a bit of a hack.
One thing I could not figure out was how to represent interlaced modes.
For the lack of better ideas, it appends 'i' to the refresh rate, i.e.
something like this:
{{{
1920,1080,60.00,50
1920,1080,50.00,51
1920,1080,24.00,52
1920,1080,23.97,53
1920,1080,50.00i,54
1920,1080,60.00i,55
1920,1080,59.94,56
1920,1080,59.94i,57
1920,1080,25.00,58
1920,1080,29.97,59
1920,1080,30.00,60
800,600,60.32,61
}}}
This is not what the patch expects and it ignores these modes, which may
be just as well since it's not clear how well they are supported by nvidia
anyway. But I will be happy to modify the script to produce whatever
format is expected by the patch.
