Regarding the TV working in the south, it depends on what TV service you have. If you use NTL or SKY then their decoder boxes work as the tuner and any TV can be used. If you just have the 'pipe' feeding direct from the wall into the back of your TV, the TV itself must have an Irish tuner, which as far as I know, you wont be able to get through the UK, not sure about the north.
