[QUOTE="globaldonkey, post: 425664, member: 49844"] Right, so its not the splitter that causes a different decoder to be used, its MP itself, which is kinda what I was talking about. Sorry for the MPC splitter red herring - it just sounded like the problem I had observed when I was trying to get MP4 streams for online videos working. They probably have the same root cause though. DS filter merits are being used to construct the graph for the m2ts file, rather than what is explicitly set in MP. When the MPC decoder is installed, it is given a much higher than normal merit 0x4000001, as opposed to CoreAVC with 0x0800200.
