When using ffdshow as codec and vobsub as postprocessing plugin I get gray bars instead of black ones everytime a video with subtitles is watched.

Has anyone experienced this? And if so, how can I get black bars on movies with subtitles?

I have been scratching my head on this one. It does not happen with my mkv's, only DVD's from disc or harddrive. Now that you have pinned it to vobsub I will play around with it tonight.
