Question

What is the difference between gstreamer0.10-plugins-bad and gstreamer0.10-plugins-bad-multiverse?

Answer 1

From the short description for gstreamer0.10-plugins-bad:

GStreamer Bad Plug-ins is a set of plug-ins that aren't up to par compared
 to the rest. They might be close to being good quality, but they're missing
 something - be it a good code review, some documentation, a set of tests, a
 real live maintainer, or some actual wide use.

The multiverse ones are in multiverse due to licensing issues.
