I’m not sure what I did to get them since I didn’t know until checkout, but I spent ~$100 (to qualify for free shipping) and they threw in a pack of DVDs. DiscSpeed4 says they’re Verbatim MCC 02RG20 4-6-8x. They have a NON-printable white face with negative (silver) lettering and a clear (wide) center. I haven’t burned one yet.
Those are most likely fake. Look at the code around the hub area and tell us what it says.
