Going out and in with a bang: newtellivision
There are roughly 24 hours left before I will switch jobs and become a "Microsoftie". My parting gift to the company I co-founded is this:

newtellivision is a framework and application for accessing live streaming television remotely. The use-case I had in mind building this is quite simple and is closely related to my current (and the new) job and the perspective of moving to the U.S. some time later this year: I want access to my local, German TV channels whenever I am traveling and I also want access to those channels when I've moved to Seattle. That's most important for two types of programs: sports and news. I care a lot more about Bundesliga football than for Major League baseball.
Consequently, newtellivision is focused on one thing: streaming video. And it comes with two user experiences that are a good choice for the above use-cases:

Windows Media Player The Windows Media Player (WMP) experience (for WMP 9 and above), is the "television to go" version. It works from any Windows PC that has Windows Media Player 9/10 installed and that can connect via any network to a newtellivision server. There is no additional software that needs to be installed on the client. All interaction with the newtellivision server is hosted inside Media Player. Features of the Windows Media Player experience in a nutshell:

Windows XP Media Center Edition The Windows XP Media Center Edition (MCE) experience is built for the "home TV at home" experience. If you move to another country and your parents or your friends host the newtellivision server for you, you can access live streamed TV programs from far-far away and your recordings right within the usual MCE experience with your remote control. And from the very same experience you have access to video blogs and web streams such as DW TV, NASA TV and thousands of other live streaming TV sources, complete with support for XMLTV guide data. Features of the Windows XP Media Center experience in a nutshell: For the Windows Media Center experience you need a Windows Media Center PC as client.

The newtellivision Server and Framework The newtellivision Server is built on the Windows Communication Foundation (WCF). The server can run either as an interactive application or as a Windows Service and the configuration wizard makes it very easy to switch between these modes. The server is extensible and comes with two plug-in providers that utilize the newtellivision Framework to provide access to live streaming video. The newtellivision Framework and the Server application are available in source code for experimentation, improvement and, of course, for customizing the existing providers or for writing entirely new providers. The server renders the list of available channels in OPML format and the electronic program guide data for each channel in RSS 2.0 format, each with the minimal set of extensions required to add vital information that is otherwise not representable in the core standard. Video playlists are rendered in Microsoft ASX 3.0 media metadata format. |

Requirements
For running newtellivision you need the following minimum server configuration:
Furthermore, for the web stream provider:
Furthermore, for the Beyond TV provider:
The Catch I
newtellivision is released in binary and source code form for any non-commercial purpose. In short, this is a "extend it for fun" application, but you can't derive any direct commercial gain from the application or any of its parts or from the operation of the application. If you'd like to use the application commercially, you must contact newtelligence to learn about your options. Commercial use expressly does not include teaching, speaking at conferences, writing books, etc.
The Catch II
This application is big, runs on beta software and is tested in only one or two server configurations to speak of. I have no idea whether anybody but me will get it to run. I've built it for myself only. It might burn your PC into a small pile of ash. I don't know what will happen. The app looks pretty polished, but evil lurks within. Consider it "alpha quality".
The Catch III
The server is, at this point, designed(!) not to scale to more than a single concurrent user. You can theoretically consume the streams from two or three clients concurrently, but there is only support for a single tuner and hence everyone has to watch the same live show. If someone switches the channel, all others view the channel too. The WMP experience is, in this case, nice enough to adjust the schedule panel to reflect the currently watched channel.
Future Direction
This is a demo app. I've written it just as that and for my personal use purposes. The reason for this public drop at this time is to avoid any troubles between me, newtelligence and Microsoft as I am making the transition between the firms. The license allows me to continue working on it privately, while all the commercialization rights up to this point rest with newtelligence. That said, I am not out of ideas. If you love writing (WCF) applications or are interested in the whole streaming TV story and you can live with the non-commercial constraint, I'd love to get you on board as an active contributor to the cause. Concretely, I'd be interested in investigating whether a provider for PPLive is feasible, whether the newtellivision server can tap the MCE streaming capabilities and whether a standalone provider can be built. See it as my next thing after DasBlog. It'll be a killer community project.
Availability
The code and the installable binaries sit here. Get them.
Meanwhile you might want to get (or go dig out) an old, used WinTV PCI card (those go on eBay for 10-15 US$) or equivalent (see SnapStream's site analog/without hardware encoding). One of my test configurations used a 1996 (!) WinTV PCI and it worked. Now my streaming source is a slightly newer Hauppauge WinTV card from 1999 that I bought on eBay.de for a whopping €10.70 a few months ago. Once you have that, it's useful to get Beyond TV configured and up and running for web streaming with the Beyond TV Web Admin interface (accessible with the "Live TV" link on the "Tasks" pane on the left of the web admin tool; http://localhost:8129 once you have installed Beyond TV). Once you get video there, you are good to go.
