I need to download some online audio/video presentations. Some of these play (streaming) in the Microsoft Media Player and some are like Webcast that play in your browser and finally some presentations use microsoft live meeting software.

How do I donwload (or capture) the streaming audio/video for all the above formats. One option I am thinking of is Lotus Screen Cam or maybe SnagIt, but these I believe are actually capturing the screens on my pc. Also the file size as I understand would be huge (as compared to the original streaming ones).

Are there any freeware/payware softwares for these purpose? Any experience using them?

Thanks in advance.
