Copy a burnt Disk?

I still consider myself a dvd noob. I have copied several of my movies onto Ritek D01 8.5gb media using my ND-3520 and DVD decrypter. I have run several quality scans with the NEC drive and the burns appear to be horrible! If I copy the movies back on my HDD can I make better discs with better media or am I stuck with the PI and PIF errors?

On a second note, what are considered the best drives for doing quality scans?

Welcome to the forum

If you can copy the data back to your hard drive, then write them to good media, the quality should be fine. I would recommend Verbatim MKM001 or MKM003

Lite-On drives are good scanning drives

Which Lite-On Writers are the best for quality scanning disks written on Nec: 16H5S, 1635S, 1693S? Thanks

All of them are good enough.

Thanks a lot.
