If a player will read DVD-R DL will it also read +R DL DVD's? I have a PS3 and a HD-A2 all the specs I have found on the HD-A2 list DVD-R DL and I have not found anything saying the PS3 can read DL DVD's at all so far. OK I was going to get some DVD-R DL disks for the HD-A2 but nobody in town has any. Best Buy, Circuit City, Office Max, Office Depot and WalMart, none of them have any. They all have DVD+R DL though (Well not sure about walmart). Anyone know?
