If you had taken the time to check, you would have seen that FiOS offers no HD on Demand. They will offer it in 2007 but not for awhile. I was fully aware of this but switched anyway as I can not one bit about On Demand, HD or not. That you were not aware of it it on you not FiOS. As for HD picture quality, I find the FiOS PQ to be better then Comcast. CSN-HD looks much better on FiOS than on Comcast. I also must question your motives here. Only 2 posts and you post this slamming FiOS in favor of Comcast. Considering all the FUD going on in the HD/BD world, I am very suspecious of these kinds of posts, especially ones that are so againt the grain. In short, if you preferred the Comcast service so much, switch back.
Louder is NOT better!
