Tivo has released their new TivoToGo service for users of all Tivo Series2 recorders. This allows Tivo users who have connected their DVR's to their home network to transfer shows from the Tivo to a Windows PC for storage or viewing. They will soon add an option to allow shows to be burned to DVD.

While I believe this is the first "official" software for a DVR that allows shows to be transferred to a PC, DVArchive has been performing a similar function for ReplayTV PVRs for some time.
