Since my copy of Primere (6.5, if that matters) didn't seem to have any innate codecs for making mpegs/mpg2 with, I went looking for a free converter program and found one that seems to be pretty nice so far:

Even though it's only a demo, the only "limitation" it has apparently is that it pesters you to buy it when you boot the program up. I thought it might be helpful for others whose editing programs also do not contain codecs for desired formats.
One also needs to remember to type in the file extension since it doesn't automatically slap it on, but if you do forget and pull it into some players it will work anyway.....
