OS X Mavericks takes read-ahead very seriously when accessing SMB drives, so it caches up to a 100 MB. However, when the end of said cache is reached, VLC will stutter because the file system needs to re-connect to the server first. Disabling read-ahead leads to a continous data flow at the media's bitrate.

This solves a regression introduced in fe0a075e

(with (uint8_t)255 << (int)24)

This will result in approx. 50% utilization
for tta files.

Media Foundation is a framework for encoding/decoding multimedia
content on Windows Vista and above. A Media Foundation Transform (MFT)
is a module implementing an encoder, a decoder or a filter.

MFTs can be enumerated and initialized using the function MFTEnumEx.
A MFT can be SW or HW, synchronous or asynchronous.

Previous code was never called for fullscreen and video-on-top.
