For PAL video (720x576, 25fps progressive / 50fps interlaced), quality gets awful below 900kbit/s, good quality requires at least 1500kbit/s. (using a good encoder and 2-pass of course.) For HDTV (1920x1080, 50i I assume) you get 5 times the pixels, so you should use 5 times the bitrate too, giving 4500-7500kbit/s. Thats 135min (4500) resp. 82min (7500) of mpeg4 video on a single layer 4.7G disc. Cheers, Udo
