enable DVB subtitles track from the command line

[dbrb2]

Hi,

Probably a basic question, but I am trying to work out how to enable DVB subtitles from the command line in VLC
I have found:

--dvbsub-position=x

Which positions them, but does not seem to enable them in the first place. I know I can enable from the GUI...

Cheers,

Ben

--sub-track 0

where "0" is the first subtitle track in the stream (and 1, 2 for the other ones).
