Starting one or two revs ago, the Preview window stopped working for me. While I can hear the audio, the window stays black -- same when in Full Screen mode. It doesn't matter which DirectShow Preview setting that I choose, all I get is audio. The Internal option, on the other hand, does show the video preview (but without audio). If possible, I'd like things the way they were a few revs ago; that is, being able to see the preview WITH audio (via DirectShow). (This is still a problem in today's update: 184.108.40.206.)
Is anyone else having this problem?
