I thought I had everything licked !!!
After upgrading 40 & 80 hr SA TIVOs with Monte, Neither one of them is recording. It goes through the motions, but when I want to watch it, it goes to "Do You want to delete? " Than it says, the TIVO could not record, because there was no video input. Which is not true. I was watching while it was recording and could go back and forth, and it looked fine, but in "TIVO Play" it shows the recordings, but the is nothing.

Now on one of the I used the software from PTVupgrade and currently it installes the software I believe 4.0.1b from TIVO. Had no problem using the network.
