Not so easy... If player feeds mpeg-ts stream to the device, track maps
are rewritten by cPatPmtParser. Also selected track is reset.

This is problematic with BluRay player: languages are not given in PMT
but metadata. There can be extra tracks in PMT when the same mpeg-ts
clip is used in multiple titles. One title can use original audio tracks
while another uses commentary tracks etc.
Also user-selected language (from BluRay menus) is overridden by VDR
when first PMT is parsed.
