been reading up on a bit on how to properly back up these great games, and i have read that i need to use 650 mb CDRs, but also some threads that swear by silverback 700mb CDRS. can it damage my system to use the 700mb CDRS? i plan to buy some high quality media and an old writer that burns really slow, but it's easier to get high quality media in the 700mb variety. thanks for the help!
