Change the default MPEG-2 demuxer (1 Viewer)

[jackdaniels]

When i play .ts files in MP it uses the MPEG-2 Demuxer according to graphedit, most files play fine, but i do have problems playing some files and it's very slow to start the movie or seek.

If i rename the .ts to .mkv it uses the Haali media splitter, plays all the movies i tested and it's quicker to start and seek.

Is there anyway i can change the default MPEG-2 demuxer for .ts files?

Thanks
