Live TV is transcoded for no reson(?)

[sprtm]

Describe the bug

1. Go to Settings -> Experimental -> check Live TV (Alpha)
2. Play any channel

Every mpeg2video stream is transcoded, but should play direct with vlckit — if I'm not mistaken? Enabling 'Live TV Force Direct Play' produces a black screen only.
