Advertisements I've gone through the set up procedure over 6 times to enable the S3 remote to use the #1 DVR switch for my S3 and #2 for my Humax DVDR-Tivo. Every time it switches both Tivo's to the last inputted remote code. This was easy when I did it with my DVDR and S2 and it went very easily a couple years ago. Yes I've covered the sensor on the other Tivo - gone to extent of overing the entire face with 2 thick magazines. Help. Without this set up having both Tivos in the same room is useless.
