real-time MPEG2 encoding isn't possible with software encoding capture
cards. You'd be best to spend the $65 or so and get a PVR-150 (regular
or MCE edition) and capture straight to MPEG-2 using its hardware
encoder. It *may* be possible to transcode from MPEG-4 to MPEG-2 after
the recording is done but I've never done that so I'm not sure of all
the steps. And this is more of a -user question than -dev.
