just wondering, i had a bunch of 350mb files, and i could pretty much fit 12 of those files in a 4.3gb space. however, the conversion process to dvd format so a dvd reader can read it only fits 6 files (half). is there a reason everything got twice as big??? also, can i do this: make iso from a bunch of .avi's using imgburn or poweriso burn iso into dvd put in dvd reader and watch on tv? or do i have to do a conversion first?
