What it is:
This is a simple video capture application for the Windows platform which takes command-line arguments such as channel, output filename, and record length, and then uses the DirectShow WDM capture interface to perform the video capture. Because it can take command-line arguments, it's ideal for use in digital-VCR or PVR applications, such as using Windows Task Scheduler to perform scheduled recording, or using a sister application which I'm developing (called JoePVR), which scans TV listings from sites like tv.yahoo.com and parses the listings based on keyworks you specify and then calls JoeCAP to record programming at the appropriate time.
