Hi. I found that my remote issues are actually like the "Slow Remote" described at the bottom of this page: Slow Remote (bottom of http://minnie.tuhs.org/twiki/bin/vie...orLockedRemote)

I quote:
- Slightly similar problem, where each keypress takes minutes - yes, minutes - to register 
  - some progress can be made by touching the remote to the TiVo's IR eye before pressing a key. 
- See if there is another device nearby that could be swamping the TiVo with IR, such as a video sender. 
  - Point the latter in some other direction or temporarily turn it off to confirm it as the problem.
