A little bit of mis information... He is some truth that may help your
understanding.
Blu-ray players and recorders will have to support playback of these video
codecs, it will still be up to the movie studios to decide which video
codec(s) they use for their releases.
MPEG-2 - enhanced for HD, also used for playback of DVDs and HDTV
recordings.
MPEG-4 AVC - part of the MPEG-4 standard also known as H.264 (High Profile
and Main Profile).
SMPTE VC-1 - standard based on Microsoft's Windows Media Video (WMV)
technology.
Sony as a studio (Columbia etc) will probably not use VC-1 but possibly
MPEG4, but other studio will use VC-1
