480i over Component?

This is silly. If the manual states that the WD TV Live supports 480i, it means it should be supported. It doesn’t matter if the support comes from composite or the support comes from component. Otherwise, the manual would state that 480i is only supported via composite.

This, in turn, would result in some very studious user to sue WD for breach of contract or false representation. Either future manuals should be changed or the firmware should be changed to reflect 480i is only supported via composite. In the meantime, should any TV be harmed by the improper wording in the manual, then it would go without saying a class-action lawsuit could ensue.
