I heard that the reason the picture quality on the inboards are not all that great is that it's actualy 4:3 but streched, not sure if that goes for all the cameras but the outboard ones seem to be like that anyway. Norwegian Tv-Media is very good at mounting inboard cameras properly, they use normal DV cameras too so quality is great.

Great DVD from winter rallies in 2008 not sure if they send out of country.
