Burning a DVD using HP computer with Windows Vista?

I'm trying to burn a DVD using my computer. The program I have been using is Windows Movie Maker then that proceeds to Windows DVD Maker. The DVD's I'm using are HP Invent DVD+RW 4x Blank discs. Every time I try to burn the DVD it works on my DVD player but the movie skips for long periods of time. Is it the program I am using or could it be the type of DVD I'm using? Any suggestions? Also I have been burning these DVD's at the slowest possible speed to try to prevent the skipping, but that hasn't helped.
