This free application lets you watch or listen to photos, music and videos from your Mac on your TiVo.

My TiVo died 4 months out of warranty and I lost over 200 gigabytes of recordings that I had been saving to watch (like whole seasons of shows). With Toast and TiVo To Go, I am able to transfer my TiVo recordings from the DVR to my Mac's hard drive, but with TiVo Desktop, I can transfer it back to the TiVo to play on my big screen TV. This is a good way to keep a backup of stuff I record with the TiVo in case it should ever die again. It might also be a good way to make more room on my TiVo's hard drive if needed.

The trick to being able to transfer a TiVo recording from my Mac to the TiVo using TiVo Desktop is this: It is a hidden trick--go into the System Preferences and COMMAND-click on TiVo Desktop (after it is installed and set up). You will then see 3 tabs, one for your iPhoto Library, one for iTunes and one for Videos. The video folder can be wherever you tell it to be. When you click to Start sharing from TiVo Desktop, you can go to your TiVo and the "Now Playing" and see a computer icon then view the TiVo video files you have on your Mac and start watching them.

I should mention that your TiVo needs to be networked with your Mac to use this software. I have mine networked with the wireless adapter and a wireless router, but you could just use an Ethernet cable directly from a router to the TiVo.

This is great software and it is free. My only complaint is that there is no user guide that comes with it and learning all the hidden tricks requires searching online at different forums. I would like to know if there are other video formats that I can view with this software on my TiVo besides the TiVo files I transfer from the TiVo. I believe there are other formats, but I don't know what they are.
