Graham Nash Songs For Beginers DVD-A Freezing Problem

I hope I picked the right sub forum..........

I just purchased the Graham Nash Songs For Beginer cd/dvd-a set on ebay. I'm having an issue with the dvd-a.

In my Pioneer DV-578A universal player, which has dvd-a capability, when I
insert the disc the menu comes up fine. However, when I select play the
machine freezes up, to the point that the only thing i can do is unplug
the player to unfreeze it. This is repeatable.

The dvd plays fine in my regular non dvd-a dvd player, also a Pioneer.
The universal player has never before had a problem with dvd-a. I also just checked it with another dvd-a, which plays fine. Any idea what's going on?

There must be something about how the disc was authored my Pioneer DV578-a doesn't like. When I remove the copyguard & burn to disc the unit still won't play the tracks; but it also no longer freezes, it just won't play the tracks.

If I set the unit to not see it as dvd-a, it plays fine in dolby audio. With dvd-a, it goes to the beginning of the track & then totally freezes.
