As further proof points on this we saw Sony Pictures release all of their titles in Mpeg2 in 2006 and Don Eklund telling us that Mpeg2 was better than AVC/Mpeg4 and VC1. Now that Sony is shipping new AVC/Mpeg4 encoding equipment, they no longer need to sell us on the superiority of Mpeg2......they are now mostly releasing in AVC/Mpeg4.
Funny coincidence huh? When they only have Mpeg2 encoding equipment to sell, it's the best codec there is. Now that they have AVC/Mpeg4 encoding equipment for sale......well you get the picture.
I've posted this all before, but I'm going to assume you didn't catch it as this thread moves fast.
