Best way to do it is by integrating WMP11 into a fresh source first, then using nLite to integrate the RyanVM packs (any and/or all). I personally made an XP by using the WMP11 integrator, then used nLite 1.2.1 to integrate the RyanVM Post-SP2 Hotfixes Pack, RyanVM DirectX 9.0c Update, RyanVM WGA Hotfix, RogueSpear .NET All-In-One Add-On, and the official IE 7 hotfix, customized the options for unattended, then made a bootable ISO. Worked beautifully. nLite seems to do a better job at integrating the RyanVM packs then the actual RyanVM integrator. Also, since there's no official support for WMP11 anywhere, I find it best to use the WMP11 integrator first on a clean XP source.
