I managed to grab a 20 pack of verbatim DVD+RDL @ 2.4x 8.5GB for $24.99 at futureshop.... I normally dont deal with these pricks and just goto a custom pc store in my neighborhood, but they were closed on sundays and i wanted to try my new xbox w/ a flashed reader and so i went there.... i noticed the 8x were like 60$ for 20 pack.... iuno mine worked great... my dvd burner only writes dual layer at 4x... but i noticed on the package it sayed it can do up to 6x... Iuno they work fine, burnt 7 games so far (wraped one already too haha) and all fine.... I have also used a maxell disc for a game and it seemed to work fine (i like maxell I use there dvd'rs for my wii and data backup... back in my psx days i used verbatim and maxell cdr's they were the best).
