To avoid churning out DVD coasters, instead set VP's options to burn an Image, which will create an ISO file. That will allow you to assess quality prior to a disk burn.
Opening an ISO in Windows 10 mounts a new drive letter (in the Explorer file manager). That drive is essentially a DVD, which can be played with MPC-HC media player and the like. When done, right-click the drive and Eject. The ISO can be burned to DVD with the appropriate software, such as Express Burn.
You can specify bitrate for your DVD video. Click the Save icon in the toolbar and select the Disc save option and click the Make DVD Movie option. Click the Advanced button to open the DVD Bitrate Settings dialog. The default option is to calculate the bitrate automatically. To set the bitrate manually, select the manual option and adjust the bitrates.
