Elgato has just updated their software to include what they claim will be the world’s first fully-functional HD DVR for all of Apple’s devices. The function called EyeTV HD is designed to record live TV in HD. It will be compatible with your iPhone or iPad as well.
The EyeTV HD just goes into your Mac and your set top box and the video can then be streamed to your iPhone or iPad. It will cost you $200 and includes the HD recorder hardware and software, a remote control and IR channel changer, USB cable, component video cables, stereo audio cables, and a switcher for composite and S-Video input.
