Thanks tinyvillager, I will check those out. If anyone else has any other suggestions, keep em coming.
I'm hoping to compile a list of these types of programs for an article on my blog. I'm writing a second article in a series on ripping streaming video and I'm going to mention URLSnooper2, as an alternative to the paid program URL Helper (made by the same company who makes HiDownload). I'm hoping to find a program w/ the functionality of HiDownload that's freeware or open source.
