I use everyone of the PoodLL plugins and can say that they all work in Moodle 2.5.2+. With them installed I can add audio or video anywhere I have the TinyMCE editor window. The lead developer, Justin Hunt, has always been very responsive and helpful every time I have needed help.
Like Jez H mentions, I have spent a lot of time looking for something to record into Moodle with and I have dropped all the others in favor of PoodLL. A recorder icon directly in the TinyMCE editor is the only "piece of the puzzle" needed to make it work seamlessly just about anywhere in Moodle.
If you would like, send me a private message and I can give you access to my current development box where you can see and try it out.
