Shouldn't need to should it? There's no Vibration to Reduce :shrug:

You might find it just has trouble simply because there is so little light coming through. IR filters, as you probably know, cut out the entire visible spectrum apart from the extreme near IR.

I think he means using an IR remote not a filter!!
I've no experience with VR, but thinking logically the VR should work whether your shooting hand held or on a tripod, shouldn't it?
I will just have to shelter from the wind and get a better tripod! The 70-300 should have 2 VR settings. One for handheld and one for tripod use AFAIK.
