Just in case anyone wanted to see the schematic for the DVP642, among a couple other similar models, I managed to stumble on it at http://pagesperso-orange.fr/doumai/Schema/DVP632%20Schema.pdf
I've got one of these same players in front of me but it blew C306 instead of C316. Unfortunately it also took out U301 with it. I can post a picture if anyone wants to see it. The capacitor didn't bulge in this case either, it blew the freakin case off and spilled the guts of the cap. Pretty awesome, probably because this isn't my player I'm fixing it for a friend. Assuming it didn't damage anything else, it should be a pretty easy fix.
