I wonder if these lines you see are actually scratches.... doesn't make sense at all.
Have you actually checked these are SCRATCHES, i.e. physical alterations of the plastic layer, that you can FEEL with your nail?
Or is this some kind of joke? :bigsmile: (no offence intended)
I scarcely print DVDs, but I print about 20 CDs a week with my IP4000, and never ever had a single damaged disc, not even slightly...
"I just tried to scratch one of my TY and couldn't do it"
Yeah, these TY DVDs are tough, tougher than TY CDs actually.
