james,
I thought the VB50 does both PAL and NTSC? If it doesn't, you can look at the ProV (it does both) although it also has the tuner built in (you can of course just ignore the tuner). If you really don't want the tuner, you can look at the soon-to-be-released BriteView (big brother of ProV). It offers component in and out (which neither the VB50 nor the ProV offer) but it will be quite a bit more expensive than the ProV (maybe 2x or 3x).
HTH
