Andrew, I finally read through the patches and they look good within my limited knowledge.
BUT, do you have any objection to moving the lines so that there are not confusing options where 720x576 and 720x480 repeat themselves -- i.e. the (w) does not show on the outer window and only after you highlight it? So the code from 0001-Add-SD-16-9-formats-to-BD-render.patch would look like below:
{ "720x576 25i", 720,576, 25., 0, ILACE_MODE_BOTTOM_FIRST },
{ "720x576 25p*", 720,576, 25., 0, ILACE_MODE_NOTINTERLACED },
{ "720x576(w) 25i", 720,576, 25., 1, ILACE_MODE_BOTTOM_FIRST },
{ "720x576(w) 25p*", 720,576, 25., 1, ILACE_MODE_NOTINTERLACED },
{ "720x480 29.97i", 720,480, 29.97, 0, ILACE_MODE_BOTTOM_FIRST },
{ "720x480 29.97p*", 720,480, 29.97, 0, ILACE_MODE_NOTINTERLACED },
{ "720x480(w) 29.97i", 720,480, 29.97, 1, ILACE_MODE_BOTTOM_FIRST },
{ "720x480(w) 29.97p*", 720,480, 29.97, 1, ILACE_MODE_NOTINTERLACED },
