Verizon has offered this with FIOS (Motorola settops) for around 2 years or more. Any SD settop in the house can play video from the "main" house DVR. ReplayTV DVRs have had this since the Replay 5000 came out around, oh, 7 or 8 *years* ago. You can use the free Java app "DVArchive" to make a PC look like a virtual ReplayTV, watch videos from any Replay on your PC, copy videos to your PC, etc.

AT&T offers this feature and requirement on their UVerse package of which I am a subscriber. We have one DVR in the living room and a set top box each in our bedroom and media room. From those rooms, we can access the recordings on the DVR. Deleting the recordings will have to be done on the DVR in the living room though.

I should have mentioned my company manufactures the Felston DD740 audio delay I mentioned above. There are two other digital audio delays that would also work in this application: Alchemy2 and Primare. The main idea is to correct lip-sync in the equipment closet on the signal "before" it is sent to all the TV's. Otherwise there will be sync differences between TV's within earshot of each other (eg: kitchen and family room) and such echoes can be very distracting.

TIVO DVR's have had this capability for many years - since the Series 2 I believe. You can watch programs recorded on one TIVO on any other TIVO in a home using either wired or wireless Ethernet. But that's still limited to display on one TV attached to each TIVO. A better solution which I have had for about 10 years is sometimes called a "whole house video distribution system". It provides the capability you mention - watching recorded material from another location - but more importantly to me, it allows every TV in the house to simultaneously display the program being watched just as if it were being broadcast live. Upgrading to HD, hoverer, poses a problem since an HD modulator requires a real time MPEG-2 encoder as well as a QAM or ATSC modulator and up-converter and so far the cheapest 1080i solution I have found is $2500. That's better than the $15K commercial equipment was a year ago but still a "lot" more than the far simpler NTSC stereo modulator I'm using to place the SD output from my four (Series One) TIVO's and DVD player on my coax. I would not trade the convenience of my existing SD distribution system for single location HD (or even for multiple location but not "simultaneous" HD) but I would like to see a lower cost digital modulator. (By "digital modulator" I mean a modulator that would accept 1080i component video and s/pdif audio, encode it and transmit it as a QAM or ATSC channel). It would be better if it were HDMI input but from what I understand the HDCP license specifically forbids transmitting anything that has been HDCP decrypted throughout the home. The application being discussed (having more than one DVR each of which can play programs recorded on the others) has an advantge if two or more viewers wish to watch different recordings - which the TIVO does - but my main application is having the same program playing "in-sync" on every TV in our home. I use a wired XANTECH IR control system to control the 4 TIVO's, DVD player, and A/V switch and a Felston DD740 digital audio delay to correct lip-sync before sending it to the modulator.

Gregory, your article is very timely given that this is approximately the 7th anniversary of MythTV. I've personally been able to watch shows recorded on my "DVR" desktop computer from my laptop over wireless anywhere in my house for almost 3 years now. The same system could also be setup with a Windows Media Center PC and available networked media players. If you wait for your cable provider, you might be waiting a long time.
