    Hi,

    I have a weird problem. Almost everything works fine, even 1080p x264 runs smooth ... but I can't get WMVHD to run smoothly. There are pauzes every few seconds, even the sound stops. If I play the same wmvhd in windows media center, it works like a charm. Even my crappy xbox360 plays them flawlessly.
    And it's not the intense scenes which give trouble, it's just weird. The bird scene from planet earth doesn't stutter for example, but the waterfall a scene before it does.

    I'm using the internal media portal player, because I want everything to be controlled by my harmony and external players don't work very good. Any idea how to fix this?

    *edit:

    I'm streaming files over my network. As I said, 1080p x264 content: no problem. WMVHD: choppy. Locally WMVHD's play fine too. So it's a combination of things. It isn't just the network, since I can play the files in windows media center from my network without any hic-ups.

    *edit2:

    Found the solution, it was a vista service designed for multimedia streaming. Killed the multimedia class service and it works like a charm now!
