The spindle of +R 4x Khypermedia discs I had were dreck. I only got 2 good burns out of 25 DVDs. On the same burner, Ritek disks burned fantastically and Taiyo Yuden nearly perfectly (and shockingly, 2.4x DVD+R CMC burn well). I would never buy Khypermedia DVDs again.
Their CDs (still CMC) are ok though.
