Unfortunately, another remote wouldn't be an option. This sound bar was for my dad for Father's Day. He is already very accustomed to the Fios remote. Changing the remote would only add more problems to the situation.
Unfortunatly the fios remotes are very outdated. There are no new codes built into it to program newer devices.
Unless you get a different universal remote such as the Harmony that was listed above.....which I bought myself new on ebay for just $40 then you are out of luck.
