No, it will also work in fullscreen mode without any problems.
(If we assume you do not use -vf scale or such) the only
thing that matters is what is in the video file.
Conversely if you have HDTV video "recorded" at a higher resolution than
your card supports, it won't help if you resize the window even to
100x100 pixels.

There might be weird circumstances including broken drivers and too 
little video RAM where this matters, but normally this should not make
any difference at all. A 1920x1080 video needs "only" 3MB of video RAM.
