The problem I think with Liberate (which is what NTL/TW use) is the interface is actually powered by some kind of web browser, and all written in HTML and Javascript. This is TOTAL overkill for an STB which won't be running at more than 50MHz.

The Sky system (based on opentv I believe) is fast because it is all native code. The only delay I have seen in channel changing in Sky is mainly due to this having to re-tune the LNB to a different signal, and wait for a stream lock to be aquired. On cable, this doesn't happen - the delay is mostly the software "getting around to it".
