I just noticed that one of my Tivos was downloading some stuff via internet. I wondered if it was a software update, so I forced a connection on my other one. It seemed to download a good bit of data, then proceeded to download the same stuff via internet (blue light). Now I have three Tivo tour videos on both TiVos. The software is listed as 18.104.22.168. Is this a new version? I can't honestly recall what the version was before these downloads.
Edit to add: I don't see anything different and the one on which I forced a connection didn't ask for a reboot. It's only the long download followed by the demo videos that made me notice anything out of the ordinary.
