Our first thought was to hook up a Roku with Nowhere DVR and Elgato's EyeTV, but perhaps there's a device that's even simpler to set up that wedges both functions into a single unit without any sort of tweaking required. If you know the inside-skinny, rock on over to the comments and holler.
I gave up cable TV last year, making do with a (not very user-friendly) HTPC running Windows 7 Media Center. I watch free over-the-air HD and Netflix, but WMC is buggy and crashes a lot. Is there a Roku-style streaming player that has a built-in TV tuner and DVR functionality in addition to Netflix, Hulu and other services? Any help would be greatly appreciated!
