Long-term stability of revVideoGrabber?

[Ben Rubinstein]

I'm embarking on a project for which I'll need to have an unnattended unit 
capturing short video clips (30-180 seconds) repeatedly over a long period; 
and need to pick my technology.

Does anyone have experience of using the rVG over a long term like this?  Does 
it hold up?

War stories, witness statements, views or suggestions gratefully received.

TIA,

Ben
