Followed your perfect directions. Incidentally, I'm using a Debian based distro called Mepis. Although it uses it's own modified kernel, I believe it's a derivative of kernel 2.6.36. I seemed to have had all the make/build components in place when I started. At least, it all seemed to work without a hitch. The 'make config' command never did result in me having to download any libs to build a config gui, but it did ask me a series of questions in regular command line format. I answered with the default option on all of them. As for the one answer a day you're providing, I am appreciative and humbled I'm getting so much. I think I would feel guilty if I took up any more of your time than that. Especially during the holiday season, especially for a device I purchased because I was too cheap to get a quality video/audio capture device. Speaking of holidays, I hope you're having a Happy New Year. I'm ready for the next step at your convenience.
