Motionbuilder and TRB data?

So, TRB is the binary format of TRC. We’ve captured a lot of data to TRB format instead of TRC at the suggestion of the MAC guy who came out and trained us.

I am super lazy and don’t want to walk down the hall and borrow someone’s Cortex (EvaRT next gen) dongle to convert the data to TRC for MoBu, but I cannot figure out how to load the TRB data into MoBu.

So is this possible, or do I need to get up and go grab a dongle (dirty!) and convert the data to TRC?

Thanks!
