Technology / Why Does Standard Definition Video Look Better On CRTs Than It Does On HDTVs?

I always noticed that Standard Definition video (from, say, VHS tapes) played on CRTs looks clearer than it does when the same material is played on HDTVs (either directly from VHS or after being transferred to DVD-Rs).
I've heard people make the general comment that the high resolution of HDTVs can "reveal limitations of the Standard Definition source," but this doesn't explain the additional blurring and artifacts one can see.
If the pixel shape of CRTs is rectangular and HDTVs have smaller, square pixels, I'm not sure why each CRT pixel could not be represented by a group of square HD pixels in an oblong shape that matches the original rectangle, without creating additional artifacts in the conversion.
