Interesting... I didn't realize that Verizon's FiOS DVRs seem to have in-house developed software, or at least, they're taking credit for it. Verizon FiOS TV Is Innovation Pioneer With Advanced Television Operating System Verizon Unveils the Next Generation of FiOS TV With Enhanced Interactivity and Personalization: Company Uses Customer Input to Create More Than 25 Innovative Upgrades to Its Powerful FiOS TV Interactive Media Guide I had no idea and wasn't terribly impressed when I rented their DVR for a week or so after my TiVo HD's internal drive when belly up/got corrupted. This is yet another one of the random pieces of DVR software floating around. No wonder it didn't look like anything else I had seen screenshots of. This all is moot for me as I have no intention of renting it again and I'm moving back to CA in a month and thus will no longer be in a FiOS area.
