Hi. I don't have Verizon Fios so I had to do some research on this. The only thing I could find were some comments from Verizon customers in 2009 that MBC had English subtitles on some shows but not all. That was before Verizon added SBS in 2010 so maybe things have changed. Perhaps a Verizon customer will read your post and give you a better answer. You could try calling Verizon directly and see what they tell you.
