I'd be willing to bet they will be using VC-1, and be very simular. I can't see Warner doing HD-DVD in VC-1 and BR in MPEG2!Ilya said:George Clooney's 'Good Night, and Good Luck' HD DVD is coming out on 8/1: day-and-date with its Blu-ray Disc version.
It will be interesting to compare them side by side.
