Our tv is on the point of dying and we're considering getting one of these Elgato EyeTV dongles thingies and using our Mac instead of replacing our tv. Has anyone tried this? Review online seem a bit mixed... Ideally we want to be able to receive Freeview channels and record to a hard drive. We live in a tiny flat and are about to move somewhere even smaller, so if we could just have one screen it would make a big difference space-wise...
