Don't have to trust you. Been there, done that.

(if anyone else sees other > benefits I missed, please do tell :) In my case I have headphones on and I'm working on a song. (Ardour/Jack/synths/whatever) I also have MythTV open in a Window. Since Jack has grabbed the sound hardware I cannot hear audio from Myth. I'm very multi-tasking and like the TV on while I write music. Music on TV increases my creativity. (OK, I'm a thief!) ;-) I've been asked to do some music for a movie. I'm sent a DVD that has some scenes and dialog. I start Myth, watch the DVD, and again have access to my music creation tools while the DVD is running. Heck, I watch a good commercial DVD and like the music. I'm in a good mood and just want to play along. Maybe I want to record the audio from th DVD along with my playing. Myth using Jack makes this possible. With Myth operating through Jack I can do my work in the studio and still have access to what Myth provides.
