* The PTS/PCR repeats we test for should at least continue for 1s before we consider it to be the EOF of a QTSS VoD session.

* if a PTS keeps repeating for a while we assume EOF. This fixes QTSS VoD which VLC kept open after it was finished.
  The limit i chose in Demux() is 5 loops of Demux() with the same pcr. It's based on nothing, but I assumed it was more safe then checking for a single repeat of a PTS value. That might be allowed in some cases????

   and the other way arround. Shouldn't change anything about how the
   thing is run)

* Now uses the fullscreen variable instead of setting i_changes |= FULLSCREEN_CHANGE since this is not handled by vout filters, and variables are.

* Only call gnome_vfs_escape_path_string on the path part of the uri, since the functions in gnomevfs that are supposed to make the host/user/path separation are broken (they will escape passwords too)
* Trying to open a file with http on a system with non latin1 encoding may still fail (testing welcomed).
* Don't call gnome_vfs_make_uri_from_input_with_dirs since this will fail on a path with special caracters, but gnome_vfs_expand_initial_tilde and gnome_vfs_make_uri_from_shell_arg

  channel mixers was broken (again) in 0.8.1 and 0.8.2; hopefully this
  will fix it for good, by allowing audio filters to request a specific
  format rather than imposing them an arbitrary one
- various other small fixes in the audio output core
- option to force detection of Dolby Surround
- simple module to decode Dolby Surround
- increase spatialization with two center speakers and fix channel
  order for 7.1 streams in the headphone channel mixer
