Thanks for the replies people, I've had a busy couple of weeks so I've only just had it back out to check and it was the fibre optic plug had come apart inside so all fixed!
The soloution I came up with for the freeview was a car tuner and aerial for £40 (xtrons) and an RF modulator second hand for £10, it was a bit of a nightmare to wire up as there's four aerials into the car t.v. but it works well with good picture quality. If anyone wants more details just send me a message
