I am not sure if this is the same situation, but I recently received a show and put it on my hard drive. Then I couldn't access the menu and only had a black screen when I tried to play the files from my hard drive.
After some troubleshooting and trying different things, I concluded that I had the video files in too many layers of subfolders.
Because I also had the same show as audio I added an extra layer of folders to put all the video files in. It seems like my video players couldn't properly access the video files. So I moved the folders to get rid of a layer of sub-folders and everything worked.
So check your directory and make sure it is setup with the same amount of sub-folders as other shows.
