A terrible truth: HD MKVs (I only have h.264 1080p files) play jerky (saccadé) with VLC but play fine with a basic Windows Media Player 9!
I tried to play with some video output options (overlay, predefined/DirectX) it won't do.
Anybody aware of that ? Any fix ? thanks
PS: I always mux with the latest MKVToolnix/Merge available
