think i'll just roll that TV and get a widescreen digital

A belated Britlish response, Verlangen: I'd understand "roll that TV" as simply "scrap that TV". The image comes to mind of a TV set rolling down into a tip, breaking apart as it does so, probably in slow motion .

However, I have a dim recollection of hearing criminals talk of "rolling" stolen goods, meaning to sell them on quickly and replace them with "clean" goods (or better yet, money).

Oh, TV criminals, of course.
