I received a reply from Pace regarding the capabilities of the Di4000, (it may be called the Di4100 - the Pace web site has changed since my original posting!), and Im afraid its not good news for CWC customers.

First the new box is NOT being distributed yet it is still in development.

Second - it uses the same IR system as the Di1000 and so will still not work with the pronto.

The NTL and CWC cable systems are not compatable and that with the merger I would thionk that they will have to decide on one system. Lets hope its the NTL one, otherwise our only hope is for CWC to respec their requirements of Pace.
