Talks about announcements in October but alas that could mean. we announce that we will have a HD PVR etc. by May 2009! Still it will be interesting, especially those comments about exclusive HD content. I am guessing it could be either channels they have now that Sky doesn't and/or on demand movies which might be downloaded to your STB and watched later or using some sort of time slip function.
But with all STB's and PVR's the content will be locked onto the box and it won't be easy or indeed possible to port the content anywhere else.
