[xine-user] Closed Caption inside user_data

[P.C. C. <pc...@al...>]

Siggi,

Found some references to the user_data stuff in the mpeg2 stream (not
sure if they are up to date.)

User data also appears as the 0xb3 header inside stats_header() of the
oms code.

Hope these would get us closer to supporting closed captioning.

Regards,
