Hi Christian,

I am sorry to say that this bug is still present with the latest 
firmware. I use the TS container and I can easily reproduce the 
described behavior. The only difference is that it occurs only when the 
first stream played is a VDR stream. The visual effect is extra black 
borders on top and bottom of the picture. I have already reported this 
bug under the networkedmediatank forum. I will make a revival too (link: 
http://www.networkedmediatank.com/showthread.php?tid=18918).

Hardware Setup: PCH-A110
