Dear dbretton, the only reason is that we must first obtain several DVD players before be able to test, how that sounds?
It sounds understandable.
I suspect that it would be rather easy to bring the DVD down to a local electronics or department store (e.g. in the US: Circuit City, Best Buy, Tweeter, Sears, Wal-Mart, Service Merchandise, etc.) and use the DVD players there.
If you have sufficient media, I would be happy to test out a copy on my home player, and I would pay for shipping both ways.
