I just bought an XL4 and the Roxio Titanium 11 to transfer files from my tivo to my mac. I set everything up but my Tivo Transfer does not "see" my DVR. If i run the Tivo Transfer program and leave it on for a couple hours, eventually the Tivo DVR will show up. Anyone else having this problem? I have contacted customer service and we've tried everything, checked all that everything needed to be enabled was, checked the firewalls, restarted tivo and computer, Checked Media Access Key, did a bunch of other stuff and still the same problem. My hardware and connection work fine. I downloaded the tivo desktop on the PC and it does "see," my DVR. Also the iTivo program does locate the DVR as well, Just not the Mac Tivo Transfer. Someone please help!!!!
