If anyone still cares, the Grease audio preservation was revived over at AMPS. I got my VHS Hi Fi captures into capable hands. And sure enough, just as this is getting synched up, a PAL disc released in the Netherlands with English PCM audio appears on Ebay.
Anybody else besides LeeThorogood have the ability to capture PAL LD's? (Specifically bit perfect audio capture.) He hasn't been on since last November.
