Query: In Response to Quality

Duncan commented on this collection having one movie per side of two sided discs, making the quality better. While I agree, and that is the reason I am buying this collection, in defense of Mill Creek, they have been using 9 Gigabyte discs for some time in their multiple movies per disc collections, although I can't say for sure that was done in the other collection he mentions. Many dvd players have in the on screen display a reading of the megabytes per second the disc is putting out. One can tell the quality by the amount it is reading. 5 megabytes per second and higher is optimum quality, and you will know you are getting the best possible by that reading, although length of the movie also determines this somewhat, and if you have a movie that is over 90 minutes, a reading of around 4 megabytes per second is still optimum quality. Movies from 60 to 70 minutes can read as high as 9 megabytes per second.
