A DVX's progressive mode is still captured in an interlaced format, so even 24p/pA should still come out of the camera from the composite output as 480i and be fully compatible with an SD TV. (I'm pretty sure you can't send 480p over composite, for that matter.) I think the weak link in your display chain here is that TV. Not because it's not HD, but because it's (in your own words) "old."
