Colorspace of DVD Q

After reading about miniDV, DVPRO25 and Beta SP, I'm curious what
the specs are on MPEG2 or DVD format ?
Are we talking 4:2:2 or 4:1:1 or some other ratio ?

Now if one uses TMPgnc, is there some control over this as well, or
or this predefined to conform to DVD protocol ?

The MPEG-2 format (as used for DVD and DVB, at least) is 4:2:0.
