This may seem stupid to ask but here goes...

:
I was trying to copy some children's music vids from three different DVDs to make one master DVD for our Children's Director. Yes, before anyone says this is illegal we are using within house and have paid for the originals. What I am finding is that when I capture using Pinnacle and play back, the sound is extremely distorted but picture is perfect. When I place a regular DVD and capture with everything the same, sound and picture is perfect. Could this be a protection issue with these particular DVDs? I hope I am explaining myself correctly.
