Mod Rewrite advice?

[CrystaStarLight]

Hi there! I'm trying to integrate PHP Fox with vBulletin. The only thing I've run into that I don't know is the rewrite codes. They seem to be incompatible, and it looks like what is incompatible is this part of vBulletin's code, "RewriteCond %{REQUEST_FILENAME} -d" seems to be conflicting with PHP Fox's code "RewriteCond %{REQUEST_FILENAME} !-d" Is there anyway I can get it to ignore PHP Fox's mod rewrite. Preferably without having to put it in a different directory.

For comparison,

Here is PHP Fox's Mod Rewrite code:

# URL Rewrite
<IfModule mod_rewrite.c>
	RewriteEngine On

	#
	#  Full path to your site
	#
	RewriteBase /

	#
	#  Rules
	#
	RewriteCond %{REQUEST_FILENAME} !-f
	RewriteCond %{REQUEST_FILENAME} !-d
	RewriteRule ^(.*) index.php?do=/$1

	# Image Access Protection
	# RewriteRule ^file/pic/photo/(.*)\.(.*)$ static/image.php?file=$1&ext=$2
</IfModule>

Here is vBulletin's Mod Rewrite code:

RewriteEngine on

# If you are having problems or are using VirtualDocumentRoot, uncomment this line and set it to your vBulletin directory.
# RewriteBase /forum/

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

# Forum
RewriteRule ^threads/.* showthread.php [QSA]
RewriteRule ^forums/.* forumdisplay.php [QSA]
RewriteRule ^members/.* member.php [QSA]
RewriteRule ^blogs/.* blog.php [QSA]
ReWriteRule ^entries/.* entry.php [QSA]

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

# MVC
RewriteRule ^(?:(.*?)(?:/|$))(.*|$)$ $1.php?r=$2 [QSA]

This is how I've attempted at merging them so far:

<IfModule mod_rewrite.c>
	RewriteEngine On

	#
	#  Full path to your site
	#
	RewriteBase /

	# PHP FOX MOD REWRITE CODE STARTS
	
	#
	#  Rules
	#
	RewriteCond %{REQUEST_FILENAME} !-f
	RewriteCond %{REQUEST_FILENAME} !-d
	RewriteRule ^(.*) index.php?do=/$1

	# Image Access Protection
	# RewriteRule ^file/pic/photo/(.*)\.(.*)$ static/image.php?file=$1&ext=$2
	
	
	
# VBULLETIN MOD REWRITE CODE STARTS

# If you are having problems or are using VirtualDocumentRoot, uncomment this line and set it to your vBulletin directory.
# RewriteBase /forum/

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

# Forum
RewriteRule ^threads/.* showthread.php [QSA]
RewriteRule ^forums/.* forumdisplay.php [QSA]
RewriteRule ^members/.* member.php [QSA]
RewriteRule ^blogs/.* blog.php [QSA]
ReWriteRule ^entries/.* entry.php [QSA]

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^.*$ - [NC,L]

# MVC
RewriteRule ^(?:(.*?)(?:/|$))(.*|$)$ $1.php?r=$2 [QSA]

</IfModule>
