pausing

I've been backing up for quite a while now, Over 300 mark, but I've noticed lately that my newer copies are pausing and slowing, like lag on a computer. I tried other DVD players. I am useing DVD Shrink, DVD Decypter, and ANYDVD. On decypter I am set at 4X burn speed, I think this is the problem, but wanted some other input also. Any idears??

sounds like the media used?

 

sorry for late W/B I'm using The TDK+R, what confuses me is the fact that not all movies are doing it? Maybe I need to go back to Fugi.... No Verbitium not in my stores or I would use them.

could be bad batch? check id codes of good burns and these new ones...
