So, do Virgin have their own CDS?
Found this article about Comcast's CDS system:

Sounds like they
were doing what Virgin do, and were copying all VOD content to the local headends for playout (or at least, that's what's been implied in the Sky Anytime thread).
Now Comcast have switched to their IP network/CDS system, they can distribute content more quickly.
Is the move to the Cisco Next-generation IP network a requisite to Virgin using a CDS? Or do they already use one of their own?
