One thing you can try is switching the TiVo Desktop server from using Bonjour to using TiVo Beacon instead for discovery. If you do this, you will need to restart both the computer and both DVRs for it to fully take effect.I have both of my Tivo premieres networked and shared . When i first set up tivo desktop i could see both dvrs. Now i can not see my second dvr to pick transfers to record. I have rebooted and nothing ?
