I just received my order of 20 DvdPro DVD-R Silver Unbranded General disks + 10 DvdPro DVD-RW. Unfortunately, they sent me 20 Princo DVD-R and 20 Princo DVD-RW. I can tell because they are identical to other Princo disks I've ordered. The DVD-R's are white, not silver. And the DVD-RWs are marked PRINCO on the bottom inner ring. And to add insult, instead of real jewel cases, they used those 1/2 cases (which break more easily). Anyone has any experience dealing with Supermediastore?
