I was just wondering, what are the manufacturers doing differently that makes one piece of blank media better than the others. IE you can buy a 50 pack of 8X Memorex's for $19.95 in stores here. While a 25 pack of 4x Verbatim Digital Video dvd's is $22.95. I have tested both media out, burning the same game at the same speed, no other major programs running other than blindwrite, and the game runs flawlessly on the Verbatim but is choppy on the Memorex. Is it something the manufacturers do? Sorry if this has been asked before, couldnt figure out how to slim down the search for 'what makes one brand better than the other'
