Toshiba sd-r5272 media problems with nero

I have a sd-r5272, it worked great with the verbtim media I orginally bought. My dad bought me, 100 generic media off ebay, here is where I have the problem. the media is Longten 002, nero tells me that its illegal disc. Please help, also I know very little about computers, so please be easy on me.

Thanks
