How do I record live streaming from lifestream.tv

[pilgrimtoheaven]

I am trying to record (download?) live sermons from thepresenttruth.org. They use lifestream.tv to "televise" live their programs. I have tried this in the past but got so bogged down in the details I gave up. I believe I used a program called avcapture? It just locked up. I don't mind purchasing a program (if the price is reasonable) but I don't know what program to get, what questions to ask or how to figure out what type of file (formatting?) is being used to stream the sermons. I have a laptop with Windows Vista, and my husband has a laptop with Windows 7. We have dsl internet. Can somebody help me please? I don't even know where to begin with this confused Thanks!
