That is a known problem. DVB subtitles can consist of multiple bitmaps.
Currently MPlayer can only display the first (since there is only one
vo_vobsub, the solution should be to just have multiple bmpsub[] and
use those instead of the single vo_vobsub that was only ever meant for
DVD subtitles - as far as I know all the code beyond like OSD can handle
multiple subs just fine).

Probably they use different DVB subtitle encoders.

Not really, just a missing feature.
