That's the nature of DVR unfortunately.
1. Can request the site play at a certain resolution, but there is no guarantee it will.
2. Capturing resolutions over 1/4 of your screen size can put intensive pressure on your machine's resources.
3. Many sites use adaptive streaming as well which means that the quality may go up and down over time, depending on your internet connection.
