I've been with Lovefilm for quite a while too and only used it for movies. I never really thought about getting jazz dvds, but then I'm not really that keen on them preferring to listen rather than watch. But on Bill's recommendation I'll have a look and see what there is anything to tempt me.
You'd have to be very picky not to be tempted by something in 800 items, John! In all fairness, though, I should add that quite a percentage of these are unavailable for rental (as opposed to purchase) for copyright reasons.
