some excerpt from the post.
You see, there is something very important, that the vast majority of both consumers and video professionals don't know: ALL modern video cameras and camcorders that shoot in h.264 or mpeg2, come with a license agreement that says that you can only use that camera to shoot video for "personal use and non-commercial" purposes (go on, read your manuals). I was first made aware of such a restriction when someone mentioned that in a forum, about the Canon 7D dSLR. I thought it didn't apply to me, since I had bought the double-the-price, professional (or at least prosumer), Canon 5D Mark II. But looking at its license agreement last night (page 241), I found out that even my $3000 camera comes with such a basic license. So, I downloaded the manual for the Canon 1D Mark IV, which costs $5000, and where Canon consistently used the word "professional" and "video" on the same sentence on their press release for that camera. Nope! Same restriction: you can only use your professional video dSLR camera (professional, according to Canon's press release), for non-professional reasons. And going even further, I found that even their truly professional video camcorder, the $8000 Canon XL-H1A that uses mpeg2, also comes with the exact same restriction. You can only use your professional camera for non-commercial purposes. For any other purpose, you must get a license from MPEG-LA and pay them royalties for each copy sold.
