i dont so much cair about the compression. the big thing a want to know is what is the size of a 2hr long 1080 HD video without any compression AT ALL ,like raw un-compressed video.

i know dvd is compressed at ether 40:1 or 20:1 (cant remember wich) but i think HD is 4x larger than standard 480.

i got the 1.8 TB idia from this problem i thout up : 32 bits per pixel, 32 bits x 1080x1920 pixels=2073600pixels. 32 x 2073600=66355200 bits per frame . 66355200 devided by 8 = 8294400 bytes per frame(8.2944MB). about 8.5MB per frame x 30 frames per second =about 250MB/s . 250MB/s x 60 seconds=15000 MB/minut (15GB/minut) .15GB/minut x 120 minuts =1800GB (1.8 TB) for a 2 hr movie!!! is my equashion right??
