I've just had an interesting conversation with the Retentions Dept. They were extremely helpful, but the main point of this is that in the course of the conversation I mentioned that Sky have a much bigger HD box available, and asked if Virgin had any plans for anything similar. I mentioned that I'd heard of the upcoming Tivo development, but never once mentioned a specific size for the HDD... The guy in Retentions then said that they are aware that as HD grows, there will be a need for it, but "I can honestly say that I've not had any information about the Terrabox"
He went on to say that if they were to release a "Terrabox" (He said that word again!), there would obviously be a big marketing push for it... Something, or nothing?
