Reading all in this thread has helped me understand a bit more about the Mac2TiVo. But before I go about trashing files in the Library, etc., let me say a little about my set up. First, I've got a MBPro 8,2 on Mavericks 10.9.2, Toast 11. My folder for transfers from the TiVo is on a partition separate from the boot partition/drive (named the partition "Storage"). I can tell Mac2TiVo where that folder is, it puts it into its window but there is a zero for files - and there are quite a number of files transferred. Is there any quirk that requires the directory of the Mac2TiVo to be in the User folder? In other words is my choice for storage a problem. I can see my MBPro in my TiVo (series 3) in the menu but it shows no files, probably because of that zero. A mention of file format was made, but I've done no changes to the files transferred so whatever format they're in is what they started as (.TiVo). The files can be viewed on my MBPro (double clicking on them) which opens the Roxio Video Player. I presume the Mac2TiVo original use was to view files stored off of the TiVo. I guess I could burn them and watch, but that defeats the purpose of the Mac2TiVo, right? I tried accessing these from my Premier and could not see any files. I have a new Romeo and an XL4 to be added to my "viewing pleasure" soon, holding off because the CableCARD fiasco pairing with the cable company - usually needs a technician to do their "magic" to make them work.
