SCOTT4 We have been using EyeTV for about a year know and this has replaced our ReplayTV unit. Although it isn't the perfect DVR solution it is quite well done. Once the computer is up and running, we can do everything from the remote and it is pretty self intuitive. The export to iTunes and/or AppleTV is great and speedy (when you use the Turbo H.264 HD stick).
The new EyeTV iPhone app is wonderful. I can stream live TV, record shows, check schedules and watch recorded shows all from my iPod Touch. I was able to get rid of my Slingbox, thank to the EyeTV app.
My parents have switched their DVR unit over to EyeTV and they have found it very easy to use.
