WD TV Live Super slow when DvD menu set to YES

I use my WDTV Live in combination with a Nas. Since som time the steaming is very slow. I cannot watch a movie anymore. After a lot of testing/troubleshooting I found out that when I put dvd menu’s to “No” in settings and I play the movie (starting from the “video_ts” map it plays fine. However when I set dvd menu to “Yes” it plays very slow so that I am not able to watch the movie anymore.

What is the solution for this problem? I do need the menu’s of course.

Thanks, Mike

Appeared to be a “broken” cable…
