i have been using nero 6 and had no problems however started using nero 7 and everytime i use it to convert and copy downloaded movie the disk stops near the end of film when you watch it. try burning at 4x and still have the same problem. when i try to make another copy from the burnt disc my acard duplicator wont recognise the disk it just keeps spinning around. i have tryed different discs,updated firmware on acard slowed burning speed and still have a problem. maybe there is a better program you could suggest! please help!
