I recently tried to copy a dvd using nero 6,I used the copy dvd option and burned on the fly at 4x. After successfully buring the disc i then tried to watch it on my dvd player and i got a message saying CHECK DISC. I have tried the disc on several dvd players and also my pc and am having the same problem. Any help would be appreciated
the best version of nero 6 is 6.6.0.18 so give that a shot It may be the media you're using sticking with Taiyo Yuden or Verbatim is the best choice.(or it may jst be a bad blank DVD this time) you're burm speed is fine, try reading it to the HD then burn instead of burning on the fly also make sure you have the most up to date firmware for the drive'burner check here http://forum.rpc1.org/dl_all.php
The only version of Nero I've ever used a... I mean, ZoSo. What I was thinking is that if the dvd you're trying to backup is copy protected, then Nero won't be bypassing that when copying on the fly. Thought come to think of it, I've never tried to copy a dvd on the fly with Nero so don't know if it'd even do it for a copy protected movie.
NOT recommended as it causes too many problems as you have found out...no doubt you used Nero Recode. What is the version of Nero 6 that you are using....as stated 6.6.0.18 is a stable version but also the latest version of 6 is also as good.
you can use nero alone with anydvd if the movie doesn't need compressed but i never recommend that or use a DL DVD and use nero +anydvd but thats far from the best option
Apart from using CloneDVD and AnyDVD, the ONLY other combination I use to back up is Nero Recode/AnyDVD without any apparent problems.
