I have a RoamioPro and we record a lot more than we watch until the off season when we can usually catch up.
I am worried that if I have a hard drive failure, I will not know what I have/have not already watched.
I would like it if Tivo could keep a list of recorded and watched shows in my account at Tivo.com instead of on the local Tivo because of the HD failure concern.
To keep the data somewhat manageable, I would even except they keep a current list of what's in my "My Shows" list and "Recently Deleted" folder.
It shouldn't be difficult for Tivo to retrieve the data on a nightly basis.
I am sure there may be concerns with privacy, but an option to disable would solve that issue.
