Capture! is a "one click web cam recording", there's no Capture! in the thread title, so that's why it's so difficult to find it.
Unlike dumb camera software that requires you to press a button to record, Capture! is more DVR like, in that it starts recording when the computer starts, saves a number of files X (with time and size contraints as options), and when the last file is saved, the first one is erased, and so on and so forth. You can also archieve in a separate directory the current file at any time pressing a button, say after a big event.
In the same thread you'll also find Capture Ultimate! and Minicam with the same features, plus displays GPS and OBD info, but they don't work equally as well for me YET.
MediaEngine of course! I'm still working on it. Plan on making it Win7 and Vista compatible soon. I finally got my car fixed (took 7 years, but hey!)
Get MediaEngine !!!
