This model Philips SPD2512T is not mentioned on the Philips firmware site. Searched web a lot and never found any trace about this model. Disc Info Tool said it is Philips SPD2512T, firmware version 1.0, finally according to my opinion very slow DVDRW. I need extreme attention when I buy DVDs since it sometimes burned such a way, nobody can use burned DVDs. If you could provide my some newer firmware RPC-1 or possibly how to crossflash it to something else faster and more reliable.
