If you have "Apply these restriction to trusted sites too" ticked in NS options (=settings), Youtube Perfect does not work, at least always.

NS version 1.9.3.3
Greasemonkey version 0.8.20090123.1 https://addons.mozilla.org/en-US/firefox/addon/748
Youtube Perfect version 1.1 (I have changed some settings in it.) http://userscripts.org/scripts/show/38074

That version is not up to date.
Please install the latest development version (first link in my sig), test, and see if your problem persists.

I installed the latest version of NS. The first video was played as expected, by Totem plugin, but as I thereafter chose another video from the "More From" or "Related Videos" section, it was played by Flash plugin as if no Youtube Perfect was enabled and as if no restriction to the plugin was enabled. Unticking the apply-these-restrictions-to-trusted-sites-too setting makes Youtube Perfect work as expected.

Finally my Youtube Perfect settings (in the script file):

// PREVIEWS: true: avoid autoplay with previews. false: allow autoplay.
var previews = true;

// EMBED: true: use MP4 plug-in. false: use the youtube flash player.
var embed = true;

// HD SUPPORT: true: force HD when available. false: never force HD.
var hdSupport = false;

// AUTO EXPAND: true: always expand videos. false: don't expand videos but HD.
var autoExpand = false;

// CORRECT 4:3: true: expand 4:3 videos to fill all width. false: don't expand.
var correct43 = true;

// AUTO LIGHTS OUT: true: auto-trigger lights out. false: don't.
var autoLightsOut = false;

// HIDE COMMENTS: true: hide youtube comments. false: show them.
var hideComments = false;

// HIDE ANNOTATIONS: true: hide youtube annotations. false: show them.
var hideAnnotations = false;

// BUTTON STYLE: true: blue buttons. false: yellow buttons.
var buttonStyle = true;

// AUTO CHECK UPDATES: true: auto check updates. false: ignore updates.
var autoCheckUpdates = true;

// DEBUG MODE: true: generate logs. false: ignore logs.
var debugMode = false;

Disabling the plugin restrictions on a Youtube page would be fine, but with the current options, I have no choice to enable plugins for Youtube pages only. And then there are embedded Flash objects for which there is YouTube Perfect - Embedded version..
