Hope you like oldies but goodies in terms of technology since Sony has made this initial decision for Blu-Ray movies. Part of me is surprised that Sony would go with the eleven-year old compression technique of MPEG-2 when they could realize increased compression with MPEG-4 or H.264. Those related technologies generally maintain video quality while taking up less space.
On the other hand, I want to say this is a smart decision by Sony. MPEG-2 is currently in widespread usage: think DVDs, over the air HDTV, and satellite signals just to name a few places. So if it's not broken, why fix it? Additionally, with the large storage capacity of a Blu-Ray disk, perhaps compression and file sizes aren't the first priority.
Again, I'm still on the fence here, so help me decide: was this a wise move by Sony or should they adapt newer and more advanced compression techniques for Blu-Ray?
