Um, I'm watching HD channels on my Mac Pro with a USB Elgato Hybrid, just screw your cable into the back of the device, scan for SD and HD channels, sign into "TV Guide" (used to be free with Titan TV, sucks that's changed), download your local channel guide, and you're set. You can schedule shows to record just as you may with your cable television DVR, and streaming them on your local WiFi to your AppleTV or iPod/iPhone is simple, and streams them using the iPhone EyeTV app ($4.99). HD channels included, the only downside is a lack of HD cable outputs, but when everything is wireless and HD, who needs it? I've only used the cables to digitize old VHS and Beta tapes, and of course those aren't HD. It was only $149, the size of a USB thumb drive, and it's about all most individuals need. In the end, it's only extreme gamers and such that need all the bells and whistles for gaming and bragging rights, beyond that it's great for most needs.
