Versions R526S0F, R48VS0D and R40WS0B respectively are now on the LiteOn server: http://www.liteonit.com/english/e-down-f.asp?show=1, all "match more media". From the file size, they are probably based on Karr Wang's new flasher.
Reports at CDFreaks indicate that the "overburning bug" seems to be fixed as well.
