I know c4eva said to use Verbatim for XGD3 isos, but does will other media work? One of the 360s in my house (my daughter's Lite-On) only reads Memorex and TDK really well. It will read some other cheap discs decently, but Memorex and TDK is what it likes. It won't read Verbatims at all (go figure). My son's box and mine both eat nothing but Verbs. I always rip & burn, then my son dupes it to a Verb and a Rex, for him and his little sis. They are ready to play Gears 3 and she only only reads cheapies, which is not what c4eva suggested. I could easily burn one and see, but I won't be home until Thursday night. Has anyone used cheap discs for XGD3 isos? (Never thought this question would come from me).
