I would imagine the DVDs should have more grain, rather than less. Grain is a fine detail in film, and shouldn't show up as well in an nth-generation syndicated copy as it would in a high-bitrate MPEG2 copy. If Paramount ran them through a de-graining algorithm before committing them to DVD, that'd suck. I don't know, because I refuse to pay Paramount's price for the series; but I remember it looked pretty good when Sci-Fi Channel had it.
