No, but the movies may have a diff max resolution from the stills.
My Sony Cybershot takes good still pics (up to 2048x1600 or so), and
poor movies (320x240 max). It's a stills camera that does semi-crap

Because when you do movies, the data absolutely has to be off the CCD
and on its way to storage within the framerate, whereas with stills, it
can take a bit longer to get better quality.
Single frames from movie cameras (except the really high end) generally
suck, but as they're going past at ~50/sec, you don't notice. Which you
*would* if you considered them individually. If I were building a
'stills too' movie camera, I'd also take a lot more care with the lens
for the same 'no-one would notice at ~50fps but if they're looking at
single shots they will' reason.
If the 'stills too' camera takes good stills, it's probably worth the
$150. But if all you're getting is a similar quality to the movie
frames, it's not, and you're absolutely right.
