If it's an old Motorola or Scientific Atlanta box you might be able to transfer via FireWire IF you both the box and PC have a FireWire port. If it's a newer X1/X3 box then you can download your "cloud" recordings over wifi if you're in a market that has "cloud recording" active. If you have a TiVo DVR you can download with TiVo Desktop or even the TiVo's built-in web server, just make sure you have a player on your PC that recognized the TiVo DRM scheme, or strip the DRM ahead of time since it's been cracked.
