Major Problem with component clashes

Hello, Need some help.

System:
Soyo Black Dragon Ultra
AMD 2400+
2 x 512 MB DDR333 (Dual channel)
2 x Seagate 40GB configured using onboard RAID 0
Sony DRU-500A DVD Burner
Radeon 9700 Pro or Radeon AIW 8500DV (I switch between them depending on need)
Windows XP

Optional (Want to install):
Hollywood Plus (PCI MPEG decoder hardware)

Problem is I have DVD Maestro (A program for DVD Authoring) which would love to use the Hollywood Plus Decoder card I have, but upon installation, it conflicts with the Raid controller and does not boot up. I have tried 3 different PCI slots, tried BIOS manually setting the PCI slot interrupt, Check the Raid controller for Interrupt settings. They both always show up in XP as attempting to use IRQ 18, Upon checking the device manager, they are both using the same INT's and IRQ's and I can not figure out how to change these. I have read that there is a slight known problem with hollywood and RAID configurations but am unable to find a solution for this. Any help would be greatly appreciated.
