Is it possible to view a previously aired show from Fios 1? I am specifically initerested in Restaurant Hunters aired on June 3
Check FiOS1 under On Demand. If it's there you can see it.
You can check FiOS1 online at: http://www.fios1news.com/longisland/restauranthunter
If neither of those have the show you want, you will need to wait for a re-airing.
