In the re-release of RC2 PGS subtitles work correctly again, thank you.
I have a request regarding them. This is already in a test build of avdvplus R11:
Would it be possible to allow PGS subtitles to be moved up and down on-the-fly when manual positioning is enabled? This already works for text-based subtitles while watching a video by binding remote keys to the "subtitleshiftdown" and "subtitleshiftup" actions.
