I've had my TiVo for 5 or so days and for the most part I'm impressed. NOT, however impressed by the TV Guide.
The guide was the main reason I got an upgraded machine. Now I've missed the whole first episode of a new season of a favourite program.
If you need help with data entry, let me know because I am more than happy to volunteer.

Also, NOT impressed that "fast forward to end/beginning" has been removed as an option. I can't imagine who thought that was a great idea.
Now it takes ages to scroll through areas I just don't need to watch.
