Well, my solution worked for me. The lower data rate had no glitch-ups
on the more critical player, which is an Akai LCD flat panel with DVD
player in the side. This player played the video thru just fine, but it
got out of sync in the audio toward the end! Must be some lousy
decoder, because the disc played just fine in our other combo player.

SO, I would like this apparently little known fact about DVD to become
well known, that the encoding bitrate can be too high for some players.
I don't know why this should be, I just call em like I see em. This has
been through the crucible of the unhappy bride, so take my word for it.
The discs that she could not play were fine on our player, so there was
nothing "wrong" with the discs, but that one factor of how I made the
discs caused all this trouble.

So why wouldn't this have come up on twelve thousand different forums
before? Why would Encore make their program work like that?
