yea, definately go with tdk or verbatim, i've had no trouble burning at 8x with those. i didn't even know there was an issue with some dvds until i recently bought a 50 spindle pack of maxells only to find that i could get no better then 2x on them. when i called applecare, they told me it was a known issue with some of the dies and they had a list of what works and doesn't. (nice of them to tell me before i wasted $30 on 50 dvds that take an hour to burn+verify 🙄 )
