With a set of analog-to-digital converters (a TiVo?) you could change the RGB+LR outputs to digital, probably legally. Certainly not convenient. Also a DVD+-R for SD (S-Video at best) or a BluRay recorder for HD., maybe.
My archiving on HDDs has gotten out of hand--currently HD films at 825, SD at 546, hundreds of series show. Come on TCM-HD.
