Might be worthwhile doing a clean install of XP as well, sorry but when you use a lot of different software, that does the same job, really can screw things up, it leaves bits so deep inside the OS, nothing will ever work reliably.
So install XP, all updates including latest Directx plus all the latest drivers for your pc, then any necessary modifications as per here, make sure all filters needed for video\audio installed (mpeg2\divx etc, make sure these work within windows ok), reboot, then install Mediaportal.
Sounds like hard work, but its a lot easier to do above, than scratching your head trying to figure out what has gone wrong.
Hopefully you should then have a trouble free experience with MP.
