Papa John, I have the Philips DSR6000 DirecTIVO receiver. I will say that the TIVO TV Activity is where I've spent 90% of my time (I've had my Harmony since the first week of October).

I have 2 Activities for TIVO; one where I listen to the TV speaker, and one where I run everything through my stereo. I found that you can either use the Watch TV activity, or TIVO TV activity to set up your PVR. There are pros and cons to both.

Basically, the Watch TV activity gives you all of the Smart Channel capabilities, while the TIVO TV doesn't (yet, they're supposedly working on it). On the other hand, the TIVO TV activity gives you all of the TIVO functionality without having to map anything additionally to the buttons or menus.

I use the TIVO TV activity, but am waiting to have the Smart Channel capabilities, and find a way to declutter the menus. I've bound the ZAP button to the Guide, and Power button (my TIVO doesn't have Power On/Off) to the Tivo menu.
