Some of the big cable operators of Europe are pushing for DVB-C2 which supposedly is 30% more efficient than DVB-C, VM have said they do not have any plans to use it though.

DVB-C and C2 define how the data is formatted. They do not define what that data is. The current Cable system uses DVB-C to carry MPEG2 compressed data. As I understand it, there is no reason it cannot carry MPEG 4 compressed data.

And yes, some cable companies do use MPEG 4..

It's unlikely that the new Tivo box will have enough processing power required to encode MPEG 4.
