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.

temporary
Temporary(4) Kernel Interfaces Manual Temporary(4)NAME
Temporary - Stores data files during transfers to remote systems
SYNOPSIS
/usr/spool/uucp/SystemName/TM.xxPID.000
DESCRIPTION
The uucp Temporary (TM.*) files store data files during transfers to remote systems. After a Data (D.*) file is transferred to a remote
system by the uucico daemon, the uucp program places it in a subdirectory of the uucp spooling directory named /usr/spool/uucp/SystemName,
where the SystemName directory is named for the computer that is transmitting the file. The uucp program creates a temporary data file to
hold the original data file.
The full pathname of the temporary data file is in the following format: /usr/spool/uucp/SystemName/TM.xxPID.000
where the SystemName directory is named for the computer that is sending the file, and TM.xxPID.000 is the name of the file; for example,
TM.00451.000. The PID variable is the process ID of the job.
FILES
Describes accessible remote systems Contains uucp command, data, and execute files Contain data to be transferred. Contain files that uucp
has transferred
