Crazy Problem ffdshow (1 Viewer)

[m0uthless]

Hello everyone!

I just build my first HTPC few days ago..
I Installed unlocked SAF6 + Mediaportal 1.1.3 + StreamedMP Skin..

But i have a crazy problem with ffdshow i think..
When i open a huge mkv video from local (22GB~) no problem, the video is fluid, no lag, everything is okay..
But when i open a remote mkv (same dimension) the video is slow, like lag (i don't know the exact term in english sorry)..

I Thinked the problem was my video card or network but i tested to play this video to on third pc with cccp coded pack installed and i have no problem.

The curious thing is if i do this operation in MPC the remote video is fluid:
- Open MPC
- Open Local mkv
- Stop Local
- Open Remote mkv (without closing MPC)

The problem is the same in MEPO.

Anyone can help me?

Sorry for my very bad english but the education in the italian school is very very poor!
