i've recently gotten a second tivo without a pal tuner and i'm trying to decide whether i should put a pal tuner in or use a stb...

i had a look around minnie and found some help on what STB to use and how to set them up but couldn't find any info about what the interface of using one is like.

so my noob quest are:

1- when watching tv, do you change channels with the STB remote or the tivo remote?

2- do you see the current program guide when you press 'live tv' like you do when you use an inbuilt tuner?

3- does the tivo sit on channel AV or does each STB channel come through on a different channel (like using a pal tuner)?

4- do the shows still record with their program name and other info?

anything else i should know?

thanks for the help.
