OC all this picture quality also depends on the Codec used and indeed which Encoder , as i understand it , many HD DVD and BR masters are still using the old Mpeg2 Codec, and VC-1.
whats the score for current HD using the AVC/H.264 Codec now as thats the only one thats got a professional lossless Encode/Decode mode, but i suspect the End users might need an even larger disk format in the future before we see 1080p+ full length features and extra's in lossless mode.
anyone done the maths for a lossless 1080p at current bitrates for a standard feature , thats got to be a rather large binary file
Snow has a lossless mode too, but thats not an industry adopted standard codec, and still needs work from the open source devs old and new, to get its speeds up at higher screen sizes really.
