[BUG] MKV Advanced Video Signaling Options Have No Effect

[potejan]

@Selur, problem with the latest dev version from today. If I set video format as "UT-Video" it forces the transfer matrix in a way where the MKV Advanced Video Signaling matrix has no effect. For example, ULH0 forces BT.709 matrix, while ULYO forces "bt470bg". The latter is a big problem because it makes NTSC processing impossible, since you can't set the correct matrix which is SMPTE170M.
