Yes, I too find it a nuisance. If you hit the 'TV' button on your remote, you can then choose a folder that is for Virgin or Sky and then select a channel. That will change tuner for you but as you say it's a real faff. Would be far easier if you could just push one button on your remote to flick between sky tuner or Virgin tuner. Especially painful when a show starts recording and it knocks the channels off on you and you have to faff about just to get back to the channel you were watching. I like getting HD on Virgin but I think a dual tuner box would have been so much easier.
