I backed a load of DVd using 5.8 of Nero ,but now Ive upgraded to NERO ,the latest Version5.9.I got problems.

Its asking for all the vobs ,even the ones i dont want to include ,to reduce the size of the film to 4.7.
Its says ...
Dvd video files reallocation
then.....
askes for required files that it doesnt need to play in INFO editor.
then says....
Video realloction failed.....
Anybody esle got the latest NERO to work.
P>S The upgrade says it solves a problem with DVD video disks .Does it mean that all my back ups I did with 5.8 are to be binned.!!!!!
