What indication do you have that "something in the syntax is tripping it up"? What are the symptoms that something is going wrong?
Of course, one might guess that part of your problem is with the command inside your for loop:
You define, but do not use, the variable NEWFILE in the command substitution that runs in a subshell environment and disappears before your for loop starts running. So, in that command $NEWFILE will expand to a constant (probably an empty string) value instead of a value based on the name of the file you're processing.
Does the vlc utility really want a sub-option of the form acce~ss=file, or is the tilde (~) in that string a typo?
Instead of throwing away the diagnostic messages produced by the code you're running (2>/dev/null), it might help to actually read those diagnostics and see if they provide any insight into what might be going wrong.
I would also imagine that invoking sed 12 million times makes your script take a long time before it ever gets to the point that it invokes vlc the first time. Why not use a couple of variable expansions inside the loop to avoid invoking sed at all? Note that this operation needs to be in a position where NEWFILE will be paired with the file value it has modified; not in someplace where the vlc command you invoke will be using unpaired $file and $NEWFILE values.

wmanager
WMANAGER(1) BSD General Commands Manual WMANAGER(1)NAME
wmanager -- choose a window manager and launch it
SYNOPSIS
wmanager [OPTIONS ...]
DESCRIPTION
The wmanager program displays a choice of the window managers listed in the ~/.wmanagerrc file. When one is picked, the related command is
written to standard output, intended to be used by shell scripts. If the program is exited without choosing a window manager, ``-1'' is
written to standard output.
-fg COLOR
Set the foreground color.
-bg COLOR
Set the background color.
-bg2 COLOR
Set the widget background color
-di[splay] host:n.n
Set the X display.
-dn[d], -nod[nd]
Enable/disable drag & drop, probably does nothing.
-g[eometry] WxH+X+Y
Set the window size and location.
-i[conic]
Start as iconified.
-k[bd], -nok[bd]
Enable/disable keyboard support.
-na[me] CLASSNAME
Set the X window class.
-s[cheme] SCHEME
Unknown, probably does nothing useful.
-ti[tle] WINDOWTITLE
Set the window title.
-to[oltips], -not[ooltips]
Enable/disable tooltips, probably does nothing.
EXAMPLE
To start using wmanager, create a ~/.wmanagerrc file - generally with wmanagerrc-update(1) - and add something like the following at the end
of your ~/.xsession file:
WM="$(wmanager -geometry +570+585)"
...
exec $WM
See also wmanager-loop(1) for a nicer way to start wmanager.
