Not a huge deal, but the HD channels filter shows I have no HD channels, but all SD channels (Fios w SD HDHR Prime)
All the other filters work though and are a huge time save, especially when looking for sports or kids shows!
While my family grew to love the On Now style, I think that my 8 yr old really likes having the grid back so that he can see what time his favorite shows will be on coming up.
Keep up the great work!
Make sure you are on the latest firmware and rescan for channels.
