Just to bump up an old thread, I just got FIOS and I'm out in Silver Spring, MD. I was having serious issues with youtube, but absolutely no issues with any other streaming site like Netflix or Amazon Prime. I used the solution posted by Hubrisnxs and it has worked beautifully. It's really simple to do if you follow the directions to login to your router and then follow Hubrisnxs' instructions. My comments are in red.

Here are instructions for doing it in the Actiontec Router, with Both bad IP address ranges
Log into your FIOS Router
Click Firewall Setting (at top)
Click Yes to proceed
Click Advanced Filtering (on left)
(Under Input) Click Add on the Broadband Connection (Ethernet/Coax) Rules you have setup (either coax or ethernet). You can check which one yours uses by going to My Network (up top) and clicking Network Connections (on left), look for the one that says connected. (I did this for both Broadband Connection (Ethernet/Coax) Rules and Ethernet/Coax Rules and it's working for me, I haven't tried it with only adding the rules to Broadband Connection Rules)
