Because you lead with "HD".
The result must be a "Video DVD" which is not HD. HOWEVER, please try DVD FLICK. I like to record the resulting .ISO (my choice) with IMGBURN.
Both are free with many tutorials.
If I ever wanted to do something stupid like share a HD camcorder file with people that have those annoying DVD players, How do I put the dumb files on a pesky DVD and make them playable in those nuisance DVD players?! I have a DVD Player. I have DVD R discs. I have DVD Flick and I have ImgBurn. I have a netbook. I still need to get a boring DVD Burner. Will a USB DVD Burner work? I can't burn the evil DVDs yet, but I have set up DVD Flick to create a .iso file. Apparently DVD Flick and ImgBurn can communicate with each other and it actually opens ImgBurn to create a .iso file
When I get a DVD Burner, and insert a DVD R (or do I need DVD RW?) ... will I be able to simply place the .iso file onto the blank and absent minded DVD? And even more simple: Would all I have do do is use the tasteless Windows Explorer to burn the brainless DVD?! And then the banal DVD will play if I put it in the ridiculous DVD player?
