My Tivo S3 is very very slow to react when browsing Unbox or Tivo Cast programs. Also it takes forever to download things It took over 4 hours to download Chuck yesterday. The file size for Chuck is around 900MB that would take around 30 minutes to download from a fairly fast server on my PC or laptop. The Tivo is plugged directly into a linksys bridge. I have Comcast cable and generally get around 5-6Mbps transfer rates, sometimes even better, using my laptop (wireless) or desktop PC. Another odd thing is that periodically the channel display pops up when I'm not even using the remote.
