The Challenges of A DVR Service 134
ChelleChelle writes "'The two burdens that are probably most annoying to the user are a complex and difficult control interface and lack of reliability.' So says TiVo cofounder Jim Burton as he describes the challenges of designing and delivering an easy-to-use yet highly effective and reliable DVR service. The article is quite broad in focus, providing information on the design aspects of TiVo (hardware, security, source code, etc) yet also taking into consideration the human element, with a large section devoted to service design principles. Overall, a good read for anyone interested in purpose-built systems." Update: 04/21 18:54 GMT by Z : Tim Burton no longer cofounding Tivo.

We have both tivos and a Comcast HD PVR (I believe made by Magnavox), and I can attest to the interface being the hardest thing to get right, but maybe the most important. And, by far Tivo has come closest to the transcendental interface over any competitors (I've also sampled the offering of some of the others).
Here are some of the "wows" about Tivo, many of which I'd discovered over time:
This barely covers the features, but Tivo has done an AMAZING job in ergonomics!
The Comcast box, on the other hand, is abysmal. It is almost unusable, but for now is the only available option to record HD shows. Here are a few of the annoyances:

Unless you happen to be watching something at 4am (actually I thought it first tries at 2am), you don't know that the TiVo is doing that. If you have something scheduled to record the TiVo grabs a later airing of that material. Eventually it either manages to record it and turns it into a showcase or menu entry (ad), or it failed to record it and skips that item.
But the user either sees all of the video played off the hard disk, or non of it. The TiVo isn't attempting to stream the video over a network while the user is watching it.
You can, with a tivo. (Score:3, Informative)
There are still some gripes with the Tivo buffering system, but this isn't one of them. Gripes:
1. It's only 30 minutes
2. If you wait too long to hit record (ie, into the start of another show) you'll only get the airing show, not the buffered one. It should ask which one you want.
3. It clears the buffer on every channel change. (Annoying to some, beneficial to others-- perhaps a setting we could switch depending on preference?)

Soon Zonk will not be confounding Slashdot with sentences like:
Tim Burton no longer cofounding Tivo.
Founding is something that is completed in the past. Pluperfect for grammar enthusiasts or those that have learned more structured languages than English is structured.
Nobody can no longer found or cofound something.

There is a swap button to switch between tuners so you're not locked to one station if you are recording it. It's at the very bottom of the remote, second from the left.
As for the front display, it really isn't that complicated:
The LED in the lower left is the power indicator (yellow is on, off is off).
The LED in the lower right, comes on when it gets input from the remote. Normally it just flashes yellow, but if it stays on, don't hit any more buttons because it is lagging.
The LED is the upper left indicates if you have any messages (red is yes, off is no).
The LED in the upper right indicates the state of the tuner you're NOT watching (the red light is on if it's recording, off if not).
The display in the middle gives the state of the tuner you ARE watching (it says REC if recording, or the time if you're just watching live TV). It will also say PLAY here if both tuners are recording you start watching a program from the hard drive.

I have had a HD TIVO for about 6 months now, it is a pretty nice unit.
I would bet the blame for lack of a standalone HDTV TiVo goes to the cable industry. They probably aren't standardized enough to make a box to allow the design of a single unit you could move from company to compnay, house to house.
MY HD TiVo does record all the Over The Air HD content that is available as well as the DirectTV stuff, a huge advancement over the regular definition Direct Tivo.
