Hey Stickmember,
The reason the Francona parts were inaudible is that there are two audio tracks for the vocals. You must have only one channel of audio inputted into your tv. If you're using a yellow/white/red hookup and only one of the white/red cables is plugged in, try switching it and the problem will be resolved. Some Tvs only have one input...just try putting the red input where the white ones supposed to go or viceversa and everything should work out fine. This is easily fixable. Call the 866 line or email me if you have any other questions regarding troubleshooting this issue.
As far as skipping, I have watched over a hundred copies and haven't seen any problems. Check it in your computer drive or a different dvd player and if it skips there too, then email me at rick@prospectmovie.com and I'll get you a replacement DVD ASAP at no cost. It's very very rare, but I'm sure there is a small chance for a dvd press error.
Hope that helps,
Rick
