This bug has been opened here: http://bugzilla.ubuntu.com/show_bug.cgi?id=15275

"When I insert a DVD in Totem I get the following on the command line:

(totem:13410): GStreamer-CRITICAL **: gst_pad_query: assertion `GST_IS_PAD
(pad)' failed

and a dialog stating:

Internal GStreamer error: pad problem.  File a bug.


This is for a DVD that loads straight to a menu.
...
> Thanks for your bug. Do you have gstreamer0.8-dvd installed? 
...
Yep. I also discovered that at least one DVD (The Life Aquatic) that opens on an
animated menu works fine, so hopefully I'll be able to use totem-gstreamer for
most of my DVDs now. The affected DVD is The Prodigy's "Baby's Got a Temper" DVD
single, which I'm sure absolutely no one else owns.

To give a better description of the problem, there's a menu fade-in and sound
plays for an initial 7 seconds (as listed on the counter), then when it tries to
switch into the mode where the menu would become active it crashes.
...
Solved the "dvdnav_get_next_block": Error reading NAV packet.." error, I've re
installed libdvdcss2, it must of got corrupted durind the install. The pad
problem only seeems to affect music videos (I've tried it on five, all region 0,
I don't know if this is part of the problem)"

Also seems to happen on Family Guy (Season 1, R4) and The Crow (R1), both of
which also complain about errors when finding CSS keys, then later that
libdvdnav can't find a suitable language (for the menus, i presume).

In the Family Guy case, it says:

GStreamer-CRITICAL **: gst_pad_query: assertion 'GST_IS_PAD (pad)' failed
libdvdnav: Language 'en' not found, using '[][]' instead
libdvdnav: Menu Languages available: [][]

This is ancient, so I'll close this. Please open a new bug if you find bugs with the GStreamer 0.10-based Totem.
