I don't know anything about dvd's. However, I just committed something
allowing requests for, say "ifo_8" to be recognized as an example of the
"ifo_%d" template, if it exists. check gst_element_request_pad_by_name
to see its current implementation, it's pretty nast but if you have a
better way that's cool. point being, you could have a general "ifo_%d"
template and allow the app to request "ifo_8" if they liked, and that
requested name could get passed to the dvd player element, as a manner
of requesting a particular ifo (whatever that is ;). I implemented it so
that one could ask for a particular channel on a multichannel sound
card, but i'd imagine the concept is analogous for a dvd.

options, options...
