The bookmark I use is https://www36.verizon.com/fiostv/web/ -- go to TV listings.
It may not work at first -- takes a while (hours? days?) . Then, a times, it's stopped working and Verizon support had to do something to re-set it for me. But, when it works it's much easier than via the remote control & TV menu.
I use the FIOS Blackberry App-- It's awesome, you can set up recordings in seconds! Schedule lookups, too.
I assume there are downloadable apps for all the other Smartphones as well...
