ReplayTV RTV5516 160-Hour Digital Video Recorder
Nice but BUGGY!
I got this unit about a year ago and love the features and the graphical user interface.  BUT...  I have been terribly frustrated with this unit's poor modem and its tendancy to freeze up.  What are they running in there - some sort of Windows-based OS?  I'm used to having to reboot my PC, but having to cycle power on what should be a real consumer electronics box is unacceptable to me.  My next DVR will be a Tivo.
