Hello RyanVM,
I have tested again with just the update pack 2.0.1 (which when alone, no problems happen) and with both the update pack and (ONLY) the official WMP10 Addon integrated with v1.0.5 of the integrator...
There is a "Setup failed to enumerate all component packages" error in SetupErr.log and on OOBE start (on first reboot), there is no music or intro movie (ie: Title.wma / Intro.wmv) not running.
Strangely enough, after install is finished WMP10 seems to be working correctly (with the mini-mode..etc.)
I have placed a link a 7-zip archive containing all Windows XP setup log files (Setupact.log, SetupLog.txt, SetupApi.log, SetupErr.log) for additional diagnosis...

This problem is also imminent with booogy's modded addon and also occured with booogy's WMP10 v1.6 addon.
