That's probably the Trevor Nunn production originally done for Glyndenbourne--Simon Rattle conducts. It also aired on American Playhouse in the US and the DVD is out in the States Mr Roxy, so you didn't need to get it transferred. It's not bad--I find some of Rattle's tempi a bit ponderous, though many love it. What irks me about the filmed version is Nunn did the odd thing he later did with Oklahoma--he restages it on a soundstage with the stage sets (though no awkward cross cuts to an audience after every big number this time) and they lip synch mostly to the cast album. I feel like it gives it a sense of feeling disconnected that just a live recording wouldn't do.
I will, when I have some money, get the BluRay of the San Francisco production. It's conducted by the conductor of the 1970s Houston Grand Opera production which is my favorite recording of the complete score (my fave other recording is the 1962 Warfield/Leontyne Price recording with the original Sportin' Life and am amazing orchestra that still sounds great--but that's just highlights and somewhat inauthentic since I believe Leontyne sings all of the big female solos including My Man's Gone Now and Summertime--though the CD doesn't say...)
Anyway, there is a clip and it looks like a solid production well filmed. Fans who disliked the Broadway version giving Porgy a crutch instead of his goat and wagon may be upset that it looks like they do the same here (at least in the sections in the youtube video...)
The SF production is 158 minutes--the Glyndenbourne production, which has every note written, is 183 minutes (but some of that may be due to slow tempi) so there have been some trims, but that's true of virtually any staging of P&G.
Here's the youtube preview.
