Dts Unbound Hot! -
If you’ve ever tried to play a movie file on your computer or media player only to get no sound or a loud static hiss, you may have encountered a DTS audio track. That’s where DTS Unbound (often seen as a feature in the JRiver Media Center software) comes to the rescue.

Great overview of using plugins in Moodle !
I would just add, that when looking at a plugin to use, as well as the functionality and version compatibility, you MUST look at the release cycle, and developer. There is nothing worse that installing a plugin, building your site / course operation around this, to find that when you want to upgrade Moodle you can’t – because that plugin is no longer maintained 🙁
I’ve seen some Universities and other large Moodle installations becoming years out of date because they adopted a plugin that didn’t;t then get upgraded.
And this biggest impact with staying on an old and compatible version of Moodle means missing out on all the new features of Moodle core.
