WD TV LIVE subtitle issues

The workaround I added is for the binary subtitle format (sub/idx or sup). SSA is text-based therefore you don’t need the workaround my bdsup2sub version provides.

In order to edit text-based subtitles you’re better off with a tool like Jubler which is for text-based subtitles. bdsup2sub is for editing the binary streams from dvd or blu-ray disks and convert between those.
