Brand for burning xbox 360 games

hi.. alot of people have been saying if you use memorex brand dvds to burn xbox 360 games it will destroy the laser in your xbox 360 and that verbatim is the brand that i should get (my friends xbx stopped working after he used memorex dvds as well..is this true because i have already burned a few games using memorex brand dvds and have been playing backed up games on my 360 using memorex..(i have a lite on drive).. thanks
