Anchor Bay did put out SP versions IIRC, but apparently they had to be “special ordered” (by the retailers)? I have found tapes (not these ones) from Video Treasures/Starmaker/Anchor Bay that have a “Duplicated in SP Mode” sticker on the back.
I remember when the “Anchor Bay Entertainment” name started popping up in the mid 90’s and those tapes often had covers that resembled the Starmaker releases with a banner placed over Starmaker’s old address and logo just so it now said “Anchor Bay Enertainment” but it stuck out like a sore thumb. I’m sure that was a rocky start, living off the assets of Video Treasures/Starmaker.
