exactly. this is why the advent of the "progressive scan" DVD player was such a big deal, and why the 480i deinterlacing is the critical step of any DVD "upscaling".
even though film is progressive (24 fps) it is stored on disc as telecined 480i/60 (since when DVD standard was developed there were no progressive displays). Being able to properly reconstruct those progressive frames is the most important step in upscaling. Properly done, upscaled SD DVD can look really outstanding on an HDTV (unlike SD cable channels which are garbage analog feeds at heart).
