Hey there. In my searches I found this post by you a while ago:
"One thing that I HIGHLY recommend is switching from the "DirecTV style" guide to the Tivo one. I had DirecTV for over a year prior, but I fell in love with the Tivo Guide in minutes AND it draws WAY faster"

I'm trying to change this on my dad's DirecTivo, but can't for the life of me find the option. Where is it?

Also, do you happen to know what changing the option in the menu system to 16:9 instead of 4:3 does? It didn't appear to change anything...
