Again, works in mx, not on 8

hi, im very poor at as, and check everything i could imagine to get this to work in flash 8.
im using the vcr simulation for www.sephiroth.it, working fine in mx2004, but not on flash 8.
the fla exceded the limit to upload, but the main actions are this:

frame 1:
fscommand (‘allowscale’,false);
var movieW = 600 // screen Width
var movieH = 200 // screen height
var inerzX = 25 // x acceleration
var inerzY = 40 // y acceleration
var maxScale = 200 // max zoom factor (in %)

// ****************
// player check OS
// ****************
playerVersion = GetVersion();
platform = playerVersion.substr(0,3);
x = movieW/2
y = movieH/2
MovieClip.prototype.t = ASNative(100,4);
stop();

and the movieclip that moves around the screen got this actions on it:
onClipEvent (enterFrame)
{
maxX = (…/:movieW/6 - ((_width)/6))
minX = (((_width)/6) - …/:movieW/6)
minY = ((_height - …/:movieH)/2) + …/:movieH/2
maxY = …/:movieH/2 - ((_height - …/:movieH)/2)
// ***************
// y axis
// ***************
_y += …/:dy
if(_y >= minY) _y = minY;
if(_y <= maxY) _y = maxY;

//	***************
//	x axis
//	***************

_x += ../:dx
if(_x &gt;= minX) _x = minX;
if(_x &lt;= maxX) _x = maxX;

}

(this i touch, are not the original for the fla dowloaded from crugnola)

anyone have a clue how to get this work on flash 8?
