My girlfriend has this issue that she's driving me nuts about. I hope someone can help me out. She has an HP Omni 200-5480qd (All-in-one) running the latest Win10 (as of Nov '16). She will burn CDs in iTunes, both AAC and MP3 formats. The AAC discs read just fine in her computer. The MP3 discs work in her car just fine but when put back in the PC show up as blank media. I see no updates available for Win10 or through HP for her machine. Device Manager shows the CD drive is functional and that no driver updates are available. She says that the discs she burned are all the same brand and we've tried several just to make sure it wasn't a bad batch. She also claims this has always been an issue so I don't think it's a dirty drive lens. Why would AAC discs read just fine and MP3 discs show up as blank (yet work elsewhere)?
