I dont even know what 4.2.2 is, but if you can point me to a sample video, I can try it for you.

edit: scratch that, I dont have an mpeg2 license. Maybe Ill order one..

Didn't see the edit soon enough. I uploaded a very short 15 sec MPEG2 clip of a 4.2.2 network show that I just recorded.

I'll leave it there or a day, and if you ever get the license you can try it if nobody else knows for sure if it will work.
I don't know much about exactly what the 4.2.2 is, but most video is 4.2.0. It's supposed to be the chroma info, and the numbers relate somehow to how many frames of different types of color info are sent, so 4.2.2 has more color info than 4.2.0.
CBS uses 4.2.2 in their feeds to the stations, and some of the other networks do too. Programs like VLC can do it, but most sat receivers don't.

If I can remember where I've seen it, I'll try to find a clip of MPEG4 4.2.2 . It's not as common as the MPEG2 version.
