I've had this issue since I began using PS3MS something like 2 years ago now.
I use it with my Sony Bravia EX TV
I run a file, it seems to load, the log looks fine, file finishes loading and then the screen is just black - nothing happens - the progress bar keeps moving as if it's playing though, and the application seems to think the file is playing fine aswell.
To get it to work, I have to close the playing file, and go back 1 directory before the file, then go back into the dir with the file and play it again - it will then play fine, and even start from the point where the previous attempt was up to while it was 'playing' under a black screen.
Simply closing the file and trying to play it again without first moving back 1 directory will result in the same black screen.
This happens with any video (i've played hundreds of them over the past 2 years), and happens 100% of the time without fail.
I have to repeat the process for each individual file I want to play during the same instance of PS3MS.
There are no errors or anything out of the ordinary in the log in PS3MS when this happens, as far as PS3MS is concerned everything seems to be fine.
What can I do to help this get fixed?
EDIT: I added all the info I could and some log files to my last post.
