I don't think this is a LOTRO issue, but I don't know for certain. LOTRO uses CoreAudio as do a number of other things, like Ventrillo and Mumble. I have "always" had a problem with audio input using Ventrillo, but not with Mumble -- lots of "hum" and "buzzing." My audio output has always been clean.

I have never had a problem with the in-game movies. (They are in the vignette_videos) folder under "raw/en/vignette_videos"
One tool you can play with -- "/Applications/Utilities/Audio MIDI Setup.app" - that may or may not help on output.
You can also play those movies directly from the Character Selection screen -- the "Movies" button on the right.
