Hi, I'm relatively new to the forum and I enjoy it a lot. Although I consider myself pretty well informed of movie related terms, there are a couple I can't figure out. CAV and CLV - I know they have something to do with laserdiscs but what exactly do they stand for? JP6 - I know this translates roughtly to "Everyday Joe who prefers Pan+Scan" but what exactly does it mean? Lastly what is MARed? I know this means modified from original version (ex open matte or pan+scan) but what is the purpose of "MAR" in caps? Thanks.
