    I've started having problems with JMP.  I think it started with version 1.12.0, but honestly a lot has updated lately so I can't be sure.

    I'm passing AC3 and DTS to an external receiver via spdif.  At first a movie will play fine, but if I pause and resume there appears to be a frame drop or sync issue with the video.  If I stop the movie, I can't restart it or any other movie.  Trying to play another movie will give me a full screen banner image or something but nothing happens.  Trying to replay the same movie will load the movie and I see it, but it won't play.  I have to restart JMP to fix it.

    I'm seeing this in the log when I try to resume.
