more tracks on cd's than the database

[Garry A. Leslie]

Hey billyo,
Can't see any reason why they would bother about copyright, they seem to have been a "fly by night" organization.
I have a small set of Music Maestro discs "Hollywood to Broadway" which won't play on any karaoke, DVD or CD player, which I had to duplicate on the computer.
The copies play fine on any machine.
The originals were all bought from a reputable firm, so I believe there is a lot of illegal stuff going on and even the reputable firms are either being taken in or in cahoots.
This again raises the question "What the hell is legal in the karaoke world, and how do you check"?
Regards from across the pond.
