This should work for you. Note that I placed an access level requirement of 10. So you will need to add the PreBot to your userlist with an access level of 10. To do this:

Alt + R
Switch to user's tab
Add the following line
10:*!*@hostmask

Where hostmask is the hostmask of the PreBot. This will prevent the script from triggering if someone other than the PreBot says for example DVD-R.

Code:
on 10:TEXT:*:#Channel:{
  [color:blue]; The message MUST match the following format exactly
  ; [-PRE-] [Type] Date:(yyyy-mm-dd) Release:(T)
  ; Where Type is any of the following: DVD-R SVCD VCD XBoX XviD Games
  ; T is any string of text, it cannot be blank[/color]
  var %r = /^\[-PRE-\] \[(?:DVD-R|SVCD|VCD|XBoX|XviD|Games)\] Date:\([\d]{4}-[\d]{2}-[\d]{2}\) Release:\(.+\)$/iS
  if ($regex($1-,%r)) {
    [color:blue]; Next check if any of the following are in the 4th token, which is the release name:
    ; french swedish danish german dutch .kor. .italian. .satrip. .pl
    ; If none of these are found, send the message[/color]
    if (!$regex($4,/(?:french|swedish|danish|german|dutch|\.kor\.|\.italian\.|\.satrip\.|\.pl)/iS)) {
      msg #echochannel $1-
    }
  }
}
