I just purchased a high-end laptop from Dell (Inspirion 8600) with a Gig of RAM, 1.7 Ghz processor, and an Nvidia 64M NV34 8600 video card with Windows XP Professional.

Along with that, I bought a Magma bus card holder, an Osprey 220 Card, and the Simulstream. Here's the problem.

Right away, I had problems doing multiple streams. Basically it was hit or miss. Sometimes the system seemed OK for a while, other times, when I went to the 2nd stream, the computer went to a Blue Screen and was unrecoverable. I have to shut down and restart. I have tried reloading all the software, downloading the latest drivers, etc., but nothing seems to help. At one point I had four streams running at once (Real 256k and Real 56k and WM 256k & 56k). The next time, when I started it, when I went to the 2nd Real it crashed. Now it seems to be crashing more frequently. I tried defragging the drive after each webcast, but that doesn't help.

Does anyone know what's going on or did I just through money away on the Simulstream?

This is probably a DirectDraw error with the VGA. turn off the video windows in your encoding app and see if the problem still happens. If it does, contact Osprey tech support.

More than likely, you do not have enough CPU "horsepower" to run 4 streams as you describe.  I am using the Niagara Max in a 2.4 gHz configuration and about the most I can get is 2 150k and 2 56k streams if I want it to run reliably.  What you do is monitor the CPU usage.  If it continually peaks at or around 100%, then you are going to have problems like you describe.  We had ours lock up a couple of times before we figured out what was going on.  Since we downsized the streams we've had no problems.  Unfortunately, since we have to provide 56k and higher bandwidth in both Real and WMP, our solution is going to be a second encoder.  We are going to get the 5225RW since it is a dual Xeon processor unit.  Should solve our problem.
