I'm using the disc named in the title in the LG GGW-H20L firmware YL02. For some reason burning a BDMV using the fastwrite option results in a disc that has playback problems in my PS3. About halfway through the picture tends to freeze / stutter - which may coincide with the second layer. One disc will even refuse to get to the menu. However burning with the fastwrite option disabled seems to be OK. Unfortunately I only have one of these TDK discs at present so it's difficult to tell if it is a disc fault. I haven't noticed the problem (yet) with the Verbatim BD-R or BD-RE 25's. The TDK disc IS officially rated at 1-2x so why does it have issues?
Any thoughts - could it be a hardware issue requiring rectification in the next firmware update or are there any other suggestions?
