What video quality is most commonly used for DVD?

From what understand the quality is around 480p to 576p. I'm no expert so forgive me if I'm wrong. Do DVDs have a maximum output like for example 720p for HDTV's or will it always be SD?

    The most common resolution is 720x480 interlaced at 30 (29.97) frames per second.

    That's not the whole of it though!  The video on the disc is compressed, but that level of compression can be varied, such that a shorter film could use lower compression and so have a higher visual quality.

    DVDs will always be SD. 

    It is that simple.

    It’s 480i because most movies in 480i are less than 4.7 gb which is how much a DVD holds. 

    You can put 4K content on a DVD but it’ll be a few minutes long because 4K is a much bigger file.
