Nero 6.6/ Hyundai Princo Problem

DVD-Writer: DVD-RW GWA-4160B (LG)

Media: Hyundai 8X / Princo 8X (Fake True 4X)

I have this weird problem. When I write in 8X to any Hyundai media burning decrypted movies or shinked movies using (DVD DEcrypter latest version and DVD Shrink last version) some parts of the movie skips :doh: , but when I write it in 4X on the 8X branded Hyundai media it’s OK.

And what can you comment about the Princo 8X color white, will this still be reliable after a year or two?

Thanks.
