I do not know what the current policy is on warranty for e-bayed players. It would be nice if Rob could hop in here and give us an official word on it.

Back in the days of the Mk1, since there were so few units, they honored the warranties even if the player was e-bayed (assuming it came from a valid owner and wasn't a stolen player). My Mk1 was this way. However, there are some factors which may make them not have this policy any more: 1) Large number of players now. 2) Owned by a different company now (SonicBlue). 3) Harder to keep track of whether or not the player was legally owned or was stolen. 4) Cheaper players and larger user base means more people mucking about inside the player and breaking things.
