As Harm said, DVD is a very specific specification. For PAL, that is MPEG-2 at 720x576, and NTSC is 720x480. Nothing else will do, these are the only formats a DVD player will play.
You can either create a proper Blu-ray disc, using MPEG-2 or H.264 for Blu-ray, or experiment with burning those files to a blank DVD, but again, those WILL NOT PLAY on a DVD player, it won't recognize the material and does not have the circuitry to play HD files. Since you will need to have a Blu-ray player either way, I would recommend just burning to BD if you want HD playback from disc.
Another option is to get a "Media Player", such as Western Digital WDTV or Roku or many others. Most of these are well under $100 and will play HD files from your USB drive or thumb drive, out to an HD display via HDMI. Then you don't need a Blu-ray player or BD discs or burner. Just create the video clips and put them on a USB stick. I should note that my Sony BD player also has a USB port and will do this as well.
Thanks
