That only works for real subtitles and not open teletext with 'w'.
That's the only way i can get subtitle and go to a teletext page manuelly.
With TVHeadend i can do in that way you say.

Maybe this is depended on the channel? Because I can activate the subtitles without open the teletext.

Many channels in sweden use teletext for subtitles and i need to do that on all of them.
I can activate subtitles but i can't select any languages, only stands None there.
In tvheadend (hts pvr addon) i could select Swedish there and same thing in VLC on same streams.
