Beyond TV 3.5 - Beyond TV Link, Clients
Beyond TV Link 3.5 is basically the same as the core PVR software title, though there are a few differences.When you first start up the software, it lists the servers on the network. Entering the UI shows a main menu that is basically identical to the server, but the server to which it is connected is displayed. Time is generated from the server, so the client's time is irrelevant to the set-up process.
The Beyond TV 3.5 server cannot be saved on the client side within the detailed settings of Beyond TV Link, but you can connect to a specific server with the proper command line:
btvd3dshell.exe /networkclient:servername.
Since conflict management is a server side issue, that option is not available in Beyond TV Link. UPDATE (written in our comment section): Btw, a slight clarification, when I mentioned that conflict management is not on the client side that was relating to the time/clock issue between the server and the client. When you schedule a recording that creates a conflict, you still need to perform conflict management, even on the client side.

We have tried Beyond TV Link on a few system configurations, including Banias/Pentium-M and Dothan/Pentium-M. Everything has been kosher thus far, even on wireless (802.11b and 802.11g) networks with 3 clients running at the same time.

This beta release doesn't seem to prompt the user with an "unable to start live TV..." window when we shut down the server manually while the client was connect. There is supposed to be a window that pops up saying that it lost the connection and is trying to re-establish.
Keep in mind that the streaming live tv over the Web Admin interface is an all-or-nothing feature. You cannot have any hardware encoding cards installed if you want to use that capability.

In a PVR250 card you cannot turn off the hardware compression...the card basically does all output through the mpeg encoder.With TV Link (network client) you can watch hardware encoded mpeg (live or recorded) via a lan, but not over the internet. It works much better than the web based streamer too.
Unfortunatly that takes out one thing important to some people. :)

#5 - It was suppose to be within a week. But it looks like SnapStream has bumped the date to early Sept.Btw, a slight clarification, when I mentioned that conflict management is not on the client side that was relating to the time/clock issue between the server and the client. When you schedule a recording that creates a conflict, you still need to perform conflict management, even on the client side.

There are 2 reasons(I know of) why they can't really stream the MPEG2 stream; it's bandwidth intensive(up to 12Mb/sec), and it requires a decoder license. Even transcoding the stream isn't very feesable, since it would require decoding the MPEG2 stream, then encoding in WMV, which may be difficult to do in real time. A seperate program is also required, and likely a specialized decoder, since by default, I don't believe that WMP knows how to deal with a streaming MPEG2 file anyhow, which may also be a problem with the codec.glennpratt - Tuesday, August 24, 2004 - link
Also, they don't have to use the Hardware Encoding features of the card, you should be able to turn it off.I don't know why they can't stream hardware MPEG2 encoding... I guess that would be a completely different way to streaming as opposed to the software encoder. MCE requires hardware encoding and you can just start playing another program on another MCE or PC while it's recording. Not exactly streaming...

Any idea of a timeframe of when this is coming out? Sept? Oct?johnsonx - Tuesday, August 24, 2004 - link
In a multi-tuner setup, I'm guessing you have to use the same encoding method for both cards; the hardware cards only do MPEG-2, and MPEG-2 is the one you can't stream.That's just my guess; I'm not at all sure.

I really wish they could find a way to allow streaming over networks if at least one of the tuner cards is a software encoder. For example, one could have a PVR-250 and an ATI TV-Wonder, with the latter being used to stream over the network.No idea why they haven't done this, but if it is a technical possibility, I wish they would do it.
Another nicety would be the ability to add program info to edited files (e.g., after removing commercials, we could add the air date, channel, and synopsis).
Can't wait for the list be folders option.
