I have the Panasonic DVHS VCR with firewire out, and I was wondering if there were any capture applications out there that would capture the HDTV MPEG2 Stream off of the VCR? Or is this a proprietary stream between the VCR and the HDTV Tuner?

I'm aware that most capture applications do DV captures, but I wasn't sure if any did MPEG2 or not. TIA!
