I've used and been happy with two shipments of 'Optical Quantum 25GB 4X BD-R 25 Packs' but the problem is I don't get the full spec amount of space to burn. Only 23098MB (~22.56GB) as opposed to the 23866MB (~23.3GB) that I assume other BD-R's give you. Can anyone that has used the WH10LS30 drive give me a name brand (memorex, verbatim, etc.) of media that will definitely give me the full amount of space. I've been using Nero 10.2 to burn.
