If the Blu-ray/DVD combo ever happened, say goodbye to the perks of the high quality transfers. Essentially what would happen to the disk is that they would have to sacrifice half of the storage space on the disc to the DVD format. Thus, they would have to use more compressed audio and video files in order to get the Blu-ray version onto the other half.

There's no loss of quality. DVD & HD-DVD didn't exist on the same surface. One was on the front and the other was on the back. No loss of capacity.
