Black screen with audio

Hey all,
I have 2.2 and installed the current version of ATVFlash but when I play MKV files I get a black screen with proper audio. when I pause the movie I’ll see a still of the movie, then play and see the black screen with audio.

I have no idea what’s going on. I think I did all the settings right. I’ve tried different files and all MKV files are the same. the files I tried were both 1080P and 720P. I did update all the udates I need for nito I know get nito instead of DVD.

Thanks

Steve.

re-encode them into what type of format?

Thanks

Steve
