Your one year warrenty would cover the E74, so you had nothing to worry about really.
The RROD would've been handy if you were over the one year, in which case the extended warrenty would come into play. But that 3 years only covers RROD, not E74.
You should get another years warrenty with your "new" box. Dunno if it'll be new or refurbed though.
