At the end of copy just before burn I get error message too much data. Do I go to custom and set a 4900?
No as 4900 is way too big for the blank media try a custom size of between 4200 to 4400.
What movie is this and which version you have for DVD Next COPY?
I have next tech &anydvd.the movie is adjustment bureau.
You can do 3 options.
Rip with anydvd first then process that rip with DVD neXt COPY.
disable anydvd and use one of the two other third party plugins and create a .bin file to make a good backup of this title.
Wait for an update.
