The VIP bundle is a fixed deal i.e it includes everything advertised within it. Start trying to remove 'extras' and it stops being the VIP bundle
If you are looking to upgrade the VIP deal then the best one to go for is VIP 50 with TiVo.
http://shop.virginmedia.com/bundles/...e-package.html It'll likely cost you less than you are paying now and give you most of the upgrades you want.
I would also suggest you keep the V+HD and swap out the SD box for TiVo, whilst rearranging where the V+HD is in your house. It will then give you the best TV options
There are lower bundles that will not include the bits you want, but whether they will actually be cheaper is something you'll have to discuss with Virgin
