Eric Clapton - Hyde Park DVD (WPBR-5)

Back in '97, when they released Eric Clapton's "Hyde Park" vhs here in the states, I noticed an ad an Goldmine that had a Japanese dvd for the same title that was listed in ac:2 format. I'm assuming this was Dolby Digital 2-channel only. The catalog number was WPBR-5).

Being that dvds were still new to the market at that point, I'm wondering what the quality was.

Of course, they have since released a 5.1 version. But, I have been unable to find any further information on the original release.

Anyone have this?
