That sounds like the nvidia driver is working properly; nevertheless we
should check if there are any problems recorded in the Xorg log. Please
run this command in an X terminal and post the output here:

grep -E '^\((EE|WW)\)' /var/log/Xorg.0.log

Other possible bottlenecks to consider are CPU load and hard disk
access. AFAIK, the older versions of the flashplugin on Linux are not
very efficient in using hardware video acceleration, so most of the
rendering workload is put on the CPU. Check the CPU load with 'top' or
'htop' while you play a flash video. It is possible that Etch's
flashplugin is too inefficient to work nicely on your hardware. To check
your hard disk access speed, you can use the 'hdparm' command.

Another thing to try is to play a flash video with mplayer, which is
usually smarter in using video acceleration. While you have a youtube
video open in your browser, you should see the video file in /tmp/; it
will be called FlashXXXXXX, where XXXXXX is a random string. It should
be possible to play this file like this (replace XXXXXX):

mplayer /tmp/FlashXXXXXX
