Question: Can I burn a HD video on my computer harddrive to a DVD and play the DVD on my DVD player?
Yes. I know there's a bunch of Linux software that does just that-- Since the libraries are free and open, there should be good free alternatives for Windows. Whatever software came with your burner probably has a tool to do that as well. Off the top of my head I don't really know what the best free alternative for Windows is. I think I put CDBurnerXP on some of my family's Windows boxes, but I can't recall if that does what you want (or even if the program has gone evil in recent years). Google is your friend.
