Does anyone have experience with Elgato's EyeTv and DirecTV. I 'd like to be able to use it to capture some items of my TiVO (ala VCR Mode) and use my iMac as a DVR in my office. I not entirely sure what Clear QAM channels are on DirecTV. I realize that the EyeTv will not be able to control the DirecTv box for recordings, but can it still capture video from the source ? Any advice ? Thanks in advance.
