Every two or three disks I burn shows banding - help

I have copied many video tapes onto DVD with pioneer DVD rec./VCR unit. On my PC I copy image of DVD to hardrive and then burn image to blank DVD using Lite-on RW SOHW-1633S using Nero. About one in three or four disks displays some banding and will not play back very well (periodic freezing, etc.) Is there a simple way to fix this? Any help would be appreciated…

Welcome To the Forum Riggo

Freezing During Play Is Usually Due To Poor Quality Media.

What Media Are You Using In Your 1633S? (Brand,MID…Etc)
And Can You Post A Nero CD-DVD Speed Quality Scan Of The Offending Media.
