Mates Rates is half price XL Plus not Triple XL
http://shop.virginmedia.com/bundles/...s/xl-plus.html which is basically the VIP bundle without the Sky Premium channels
So the same TiVo rules apply. If you have an older XL Plus with 20 or 30Mbit, V+HD and V HD then swapping one of them to TiVo adds £3 a month on to your existing price. If you have 50 or 100Mbit the new bundle price will include the TiVo monthly fee
