Ritek R03 and NEC 3550A read error

I just bought 100 pieces Ritek R03 DVD+R media and everytime I burn a movie I always get error almost at the end of the media when running Nero CD-DVD Speed scandisk. I have the latest firmware 1.06 and used nero and dvd decrypter to burn the movie with the same errors. Im running windows media center.

Is there any solution to this? So I can get error free backup? Thanks much.

Burn them slower or reduce the size.

Thank you. I’ll try it out.
