(I suppose I should actually attach the file ... ;-)  )

OK - here's a ZIP file with mashvtc.exe and a ZIP file with the source.

What you have to do is use mashvtc instead of vtc for both the display and 
the video streams.  Use it exactly like you would vtc.  What I did was 
massaged the output from the bridge to give mash the appropriate input 
parameters.  You need to still use the original vtc for the RAT.

I haven't done a LOT of testing on this, and others are welcome to extend 
and/or fix.
