I know there are a couple of reasonably priced SDI output mods available but has anyone here ever installed one in a freeview/gondigital box. I've seen places that offer modded sky digiboxes but I'd like to get an idea of how tricky these things are to install. The companies that offer pre-modded units seem to charge a fairly hefty premium for them. Spending many hundreds of pounds just to get a slightly better picture out of freeview isn't really an attractive proposition. A couple of hundred for the mod and card then fine, but another couple of hundred for installation no way.
