Jerky playback from backed up region 1 disk

Hi,

i have brought a copy of finding nemo from the states, i have tried backing it up, the disc plays fine in my computer but not in my stand alone? however any of my region 2 disk i backup works fine in my stand alone?

im using dvd decrypter and dvd shrink, nero 5 to burn

 

Try hacking the standalone player with a remote crack....I did that and it worked for me.
