TURN-ONS AND TURN-OFFS IN CURRENT HOME ENTERTAINMENT RELEASES : ExcellentGoodFairPoor : VIDEOCASSETTES

“Thursday Afternoon.” Brian Eno. Sony. $29.95. Like his ambient music, Eno’s lulling video is not meant to be watched like a football game or the latest Duran Duran opus. These sl-o-o-ow-motion nude and seminude studies serve as luminous paintings, the optically treated images verging on the abstract, so Hef can breathe easy. The 82-minute piece might work best casting a glow in a corner at a party, like a fish tank or a lava lamp. It involves you most before you watch: You have to turn your TV set onto its right side to view the vertical images. Ready . . . lift!
