MAC Tivo Transfer BACK to my TiVos

Hi.

I bought Toast 11 for my MAC and downloaded and installed TiVo Desktop for MAC. I'm able to see my TiVo recordings and transfer them to my MAC without issues.

I cannot however transfer them BACK to my TiVos. When I pull up my MAC on my TiVo's it says: The iMac (blah blah) has no recordings.

Suggestions?

Don
