I've recently bought a Sharp Aquos LC26GA4 and the picture quality isn't that good using our second room subscription Sky Minibox. I think this is mainly because it doesn't have RGB out so I' like to buy a box which does and was wondering the best way to do this. I'm on a fairly tight budget and don't want to spend more than £100 (£50 would be nice!), so I guess I'll have to purchase a second hand box on Ebay or from this forum. A couple of questions then: 1) Which box should I be looking for? 2) What's the procedure to change to a different digibox? - do I just plug it in and insert my existing viewing card (currently in the Minibox) for it to function, or do I need to ring Sky for them to re-enable everything? Thanks for any replies.
