I emailed Ceton through Amazon so hopefully I'll get some money back from my purchase 2 weeks ago.
My complaints about the Comcast DVR were:
1) the UI is terrible and inconsistent.
2) the capacity was small.
3) no 30 second skip nor comskip integration
4) only 2 tuners.
I now have 6TB of recording capacity (shared with MyMovies) and can use comskip again. The Ceton adapter gets you an additional 2 tuners as well.
