Removing/Changing MD5 on Passwords

[wh005h]

Here's my problem:
I have a a server that reads md5 and regular passwords. The problem I'm having is Vbulletin encrypts the passwords differently than the server and they don't sync up as the same hash.
I need to either: 1. Remove the md5 encryption entirely or 2. change it to the same thing. I'm seeing removing it as an easier thing to do lol

The md5 for the server works fine and dandy by just putting md5 infront of the password post on insertion. Vbulletin seems to go a little beyond just that lol.
Either that or I have absolutely no idea what I'm talking about and it's something totally different ¬_¬

**Edit**
Okay after reading some more I found that out that I need to remove the "salt" from the hash to keep it as the hash of just the password. Anyone know how to do that? I would really appreciate it ^_^

**Edit2**
Okay read some more... I just need it to be just md5(password) lol no salts or double md5
I've found incomplete guides most of which don't even do half of what they say lol
