Way back when Sorenson came out, there was a software transcoding package that I just cannot remember the name. It was commercial and available for Mac and PC. It wasn't Squeeze. They sold a Mac version and a PC version separately. We had both platforms at the time, but only the budget for one. We settled on the Mac version. Funny thing, the CD installer was a dual format. On the Mac, it would show the Mac software, but when placed in the PC, it would show the PC software. So one purchase, both versions. It wasn't sold/advertised this way. They meant for you to buy a copy per OS. Can't help they were dumb about it to save a few pennies.
