Yes, but deinterlacing is trivial (and low cost) to do in playback.

Unless you're using a high-def TV in progressive mode, then this is
because the TV image _is_ interlaced (that's why the video is
interlaced in the first place).  Playing an interlaced video on an
interlaced screen will appear exactly as it was meant to, whereas a
deinterlaced video will have lost quality through being deinterlaced
during encoding and then interlaced again on playback.

PVR = Personal Video Recorder (i.e. tivo, mythtv, etc).
SDTV = Standard Definition TV
