Is there any way possible to edit the Garcenote cddb database.

Nope, not that i'm aware of and we should not have to. Pioneer needs to step up to the plate and issue another update.

Plus, if you look for your cds on Gracenote, they are typically there. Pioneer is just lazy and doesn't want to fork over the money. If Pioneer was on top of it (esp for a system that's $2k to buy), this complaint would no longer be valid.
