Thank you for your input Edg1!
I did put the Moca bridge in place of the Verizon Router. I figured out late last night I had the moca bridge in the wrong location in my house. I thought I had it on the main coax cable line coming into the house but realized I had it on one of the sub-lines. Once I placed the moca bridge on the main line, everything worked fine with both FIOS TV boxes. Thanks again for your input.
