Any R-Mix Video Tutorials out there?

I've been busy with other things for a while and want to start the New Year off with a music project and just pulled down and installed the X2a update. I've looked at the help file and a few of the Roland R-Mix Videos but I'm looking for an R-Mix tutor of some kind. I've played with it but really think it could open up some new possibilities.
 
I purchased both Craig Anderton X2 video's but at a quick glance do not see anything in regard to R-Mix but could be missing something. I also have Karl Rose's excellent Complete Sonar X2. I just can't seem to find something detailed on R-mix. I also checked out Cake-TV but that left something to be desired.
 
So is there anything out someone could point me to that I've probably just missed?
 
Thanks,
 
Joe..

I gained a much better understanding of R-Mix by watching Brandon and Seth's Webinar.  They play around with it and talk about it enough to get a good starting point to work from.  Unfortunately, I couldn't tell you exactly when in the hour and a half video that they cover it.... everyone should watch the whole thing anyway. That and (Seth's) "transitioning" video made my transition from 8.5 much easier...

Best,
Rob
