Thanks guys!

My response was to willyb, whose program looks like the same thing, except for windows. I've downloaded RSRConv, and will use it next time. I did manage to get P7 to do the job, so I don't have anything to try it on right away. 

Ugh, using P7 now is painful! As much as I hate the decision to add Flash to Poser, I must admit the new library in 2012 is so much better. The library in P8 is almost tolerable, but still kinda creaky. But, P7 (and presumably earlier) reminds me of the bad old days when we were stuffing MAT poses in the Camera area to avoid to have to dig through so many items in the main folder...crazy times...
