I am a user of cd / dvd toys. My bluray recorder is a Pioneer BDR-S09XLT, I was able to record BD-R and BD-R DL (50 GB). The problem I've seen is that the BD-RE (rewritable) identifies them but does not show the capacity of the disc that can record, resulting in recording impossible to do.
The engraved bluray can be read in both windows and linux.
