Hmm, sounds like a typically-Virgin response to genuine concerns. They're all about their trendy informal branding nowadays.
The TiVo thing looked interesting until I realised it was inexplicably tied to Virgin Media. Could I buy the TiVo box seperately and hook it up to Freeview or Sky if I no longer wanted my Virgin subscription? Er... no. OK, so having bought the box surely I wouldn't need to pay more of a subscription charge to Virgin? Er... no again.
As I'm already stuck with them for 12 months after getting a HD box upgrade without realising that tied me into another 12 month contract with them (I double-checked afterwards, and there was no mention of a new contract from the pages I signed up from) I can't see myself ever signing up for this sort of thing from them.
