Play bug?

I bought this player about 3 days ago and I have an anoying problem: after 25-27 min. of playing movies (mkv, avi etc.)  the movie browser (menu) pops in but the movie soundtrack keeps playing. So, I have to push the play button again and resume playing. Is this an issue, bug or a setting that I didn’t see ? Thanks.

Does it do this with ALL movies, or just specific ones?

Does it do it at the SAME POINT every time? 

  If so, what happens if you fast forward through that point?

Yeap, with all movies at the same point (of time). I  have not tested with fast forward but I guess this is not a solution…
