i have a very weird problem w/ my emac. it is 1GHZ w/ 512mb of ram. it reports itself to have a superdrive in system profiler, but it will not read the dvds i put in it. it reads my cds just fine however. any suggestions? also would i be able to clone my macbook's hard-drive onto the emac and make it run leopard. i know the emac can take leopard, but is the stuff on my macbook universal or not. thanks for your help.
