the intolerant remark was said with a smile :) .. that means I am not serious... As for size..thats what I care about. Even if you have a 1-1.5mb cable modem 5 megs still takes a bit to download, and everyone in business knows that time = money. If mpeg4 will get me 640x480 at under 5megs then I am going to use it. The Mac factor is insignificat in my world..we usually only have 2 or 3 people a year complain about it, and when they do we just send them a vhs copy. When qt6 is released with mpeg 4 we may switch to it. Our advantage now is that our Avid will export the mpeg4 in about 3 min on a p3 500...to make a quicktime of lesser quality averages us about 10-12 min a spot and we have to use a third party program.
