Hello I seen a post a while back abot some1 asking if these disks are any good as they were onsale at BestBuy 15 for like 20$. some1 else replied that they are good and he/she has used them. So I went agead and got a set. Well I burned a copy of my Lost Planet game to test it out (original disk not a downlaod or anyhting) i popped it onto the 360 drive and it sat on reading disk for like 2mins and then finaly said Unplayable disc. Well i have made some other copies of my orignal games using Memorex DL disks and i havent had a problem. I did it the same way i did the others. So i was wondering is it the media is why it cant play the game? I have Samsung MS28 with the newest xtreme firmware 5.2D. If it is can i take this back to BestBuy? if i do that what do i do with the disk that has the game on it?
