I got the E74 error, I'm sending it back to Microsoft for repair(not under warranty). My question is, will they send me mine back or a different console. The reason I'm asking is I'm having problems with the disc drive sticking ( not wanting to open)and I'm hoping I get a different console back. Or should I call them back and tell them the disc drive has problems also? Will they replace both parts for the $99.00 charge???
