Mezzmo Issue With Subtitles (always on)

[DMViolator]

Hi

Been using Mezzmo for a good while now with no issues, until yesterday.

I have Mezzmo 3.1.1.0 installed, streaming to an Oppo 93/Sony KDL-EX653. Basically the problem I have now is that whenever I stream a movie (BDMV container) that has subtitles in it, they are always displayed on-screen. I can only turn these off by selecting Subtitles on the Oppo (which shows off by default), selecting any subtitle track, then choosing off again. Then they disappear.

I have turned off every subtitle setting I can find in Mezzmo, and unticked the boxes in the file properties. Still the same.

If I hook up an external drive directly to the Oppo and play the same files, there's no subtitles displayed. And up until yesterday, there weren't any when I was streaming.

Not made any changes to Mezzmo that I'm aware of. Have uninstalled/reinstalled with same result.

*edit* I should mention that if I stream directly to the TV, there's no subtitles shown either.

Any help please?
