Hi Ed,
Just an FYI...
I have DirecTV, we have had the locals in HD since August/September.
Yes, extra boxes are $4.95 extra a month for mirroring, but I believe if you add more than one, it's still $4.95.
I got my HD DVR last February for free, no up front charges.
No FIOS here in Greece either, I would like to trial it.
At the very least use the above info when your TWC expires, get the most for your money.
Jim
