[QUOTE="Doodler, post: 1635, member: 175158"] One thing for sure, the sound is going to be way better from a DVD if you have a Dolby Digital decoder or amp, so give me the DVD any day! As for picture quality, (what follows is based on my very limited understanding) basically it's down to the amount of bandwidth applied. As ChannelHopper pointed out, this can be variable in the case of DVB, and although there is a limitation I don't know what it is. In the case of DVD there is a maximum of about 4GB (700MB is for CDs). Most DVDs include a lot of extra material, so let's say 3GB and if the average movie is 1.5 hours that equates to an average of 33MB per minute or 550K (bytes) per second. Anyone know how this compares to DVB bandwidth? I guess for either DVB or DVD a given level of quality is going to require more for action scenes (with lots of movement onscreen). [/QUOTE]
