I searched Google and found this great Over-The-Air DVR that works with the Revue called the Channel Master.
This means you can receive OTA channels in HD for FREE with no monthly cable / Satellite costs whatsoever! All you need is this box and an antenna to get full DVR capabilities without paying monthly fees for it. Even TiVo charges a monthly fee but people are leaving TiVo for this one. Not to say that TiVo is not good. Just saying that if you are looking for a totally free solution, then this may be for you.
Here are some of the reviews on Amazon:
Amazon.com: Channel Master CM-7000PAL Digital Video Recorder, Black: Electronics
This is a great find considering the technology for receiving OTA signal for HD channels combined with a DVR is so rare. I could not find any others like this one online from different OEMs.
Here it is for $50 cheaper.
Hope this helps some of you.
