They must have made a ton of these.
What a shame that the DVD Forum folks let themselves become involved in trying to compete with SACD's CD compatibility when they should have stuck to their own format and promoted it heavily instead of diluting it's potential by adding the confusion of the insane DualDisc. Ranks up there with "New Coke"!
To make matters worse, their competition (Sony) got involved in the "unifying format" and spoiled the pool by filling the racks with crappy DualDiscs offering nothing more than a few videos and an audio track that made little difference to anyone.
Talk about shooting themselves in the foot! In retrospect, they should have taken the DualDisc funds and subsidized hardware manufactures so that EVERY DVD player sold had DVD-A compatibility, even if it was only stereo on the cheaper players, so that market penetration would have been bigger.
Oh well, once again the IF word rears it's ugly head..................
