Playing Downloaded HD Movies on Your HDTV

If you do not have an HD monitor for your PC or Mac, and you download a nice big 1080p HD porn movie, you probably want to watch it on your HDTV.  To do this, you need at minimum an HDMI output on your computer / laptop.  Then you can plug it into the HDMI input on your tv, play the movie on your computer, and you are all set.  For people without and HDMI output, you can’t watch it on your tv, just your monitor.  Obviously, this is a pain for those of us with just desktops.  Unfortunately, I have not found a way to burn HD movies (either MP4 or WMV) to a DVD in HD.  If anyone knows how to do this, please let me know and I will post the solution.  Thanks.
