If I press print screen when a video is playing at any given resolution,
do I gain resolution by going full screen and then pressing print

Use VLC and take snapshots with the hotkey.

WHY do people not READ what someone says?

He has clearly said, several times, that he's talking about using the
video player functionality of various websites, such as YouTube, and is
_not_ interested in downloading the videos.

Downloading videos is for *research purposes*.

Using carefully controlled conditions on your own
desktop, you can observe what things do and do not
give extra resolution.

Once you *understand* what is happening, you can
use any method you want.

You cannot take screenshots of Flash videos where the
Flash plugin is using "Hardware Acceleration". The
same can happen in VLC (if it uses hardware acceleration,
the movie frames are in the wrong plane). If the
browser has native video support (like Ogg/Theora
perhaps), again, there can be various attempts at
acceleration which defeat PrtScn.

So PrtScn is not a panacea. FRAPS can "record anything",
but, it costs money. Various other tools may record
from one of three planes, but FRAPS is the only
one that offers all three planes of coverage when
recording.

You can also record your screen with a hardware
capture card, which takes some of the protections
out of the picture. If the software makes a concerted
effort to use HDCP, then you could be denied capture
with a capture card.

This is why *downloading* the movie, helps...

No matter what the OP posts, we can *still* offer
hard-earned advice!
