From what I can remember its goes something like this

when Qui gon died there was balance in the force so he was burned on the Pior which is jedi tradition

then later on there is imbalance so he finds a way back via the force

the imbalance is so strong that OBI & Yoda disolve into the force at the time of their deaths

when Vader dies he has restored the balance to the force by killing El Sid, & as a result luke Burns his remains as is the tradition.

Never heard that one. Why couldn't Lucas have made it easier? Oh yeah, he didn't watch the OT when he was writing the PT, and only addressed issues as they were pointed out to him, promising answers in "the next movie."
