In the audio drivers section, how do the two cards look? Does RB just list in and outs 1-16?

Have you tried playing a song with both units connected for playback, but using a selecting a different audio input device? If it happens right away (like you say), maybe something is coming back in that causes it, and you could see by this test if it is the input side or the output side of the MOTU.

Just a couple shots in the dark.

Maybe even try setting RB to use a discrete thread in the options area. This has solved some weird problems before.
I assume you've tried each unit separately to make sure one of them isn't causing something in RB to go kreplunk .. I know they work in Sonar, so not likely, but we're just looking for clue (as Oren says)
