What is the file size of the HD video?
Are you trying to burn to DVD 5 (4.7 GB size) or DVD 9 (Dual layer: 8.5 GB)?
VideoReDo is going to be about the best you're going to get (IMO) as it automatically adjusts the bit rate so that the majority of the disk space is used.
ETA:
If DVD resolution is unacceptable you're going to have to look into getting a Blu-ray burner, or AVCHD to make HD DVDs that are playable on a Blu-ray player.
