I'm currently transferring shows from a Series 3 over wifi, which I know isn't supported. This is maxing out the wifi, so the Roavio is having problems getting any other network data.
I was watching football behind the buffer, and had added an hour to the end of the game just in case. When I reached the end of the game, the show was still recording, so I tried to stop the recording. TiVo told me that there were network problems and I couldn't do that.
The TiVo shouldn't need to check with the network before manually stopping a recording.
(It was an autorecord wishlist, if that proves to make a difference.)
