My very first batch was the 25-pack of the Ritek G04s, and they are what they advertised. Five of the 25 discs had problems writing the lead-out, but other than those, the rest all burned well.
i don't know about oem, but the ones i get usually matte finish on one side, and of course purple on the other, ive never seen blank dvds with silver on the writing side
