It can be a compatibility problem of the drive with the disc. Now, which is to fault? Both?
Try another good brand media (Taiyo Yuden, Fuji, even Moser Baer India or later generation Ritek) to see if you can get less errros.
BTW are you doing the Nero CD Speed scans on your Yamaha F1? The error reading accuracy of that drive is not particularly good, so I wouldn't trust those results completely.
