I'm reinstalling XP Pro yet again and the default WMP9 can't play some of my favorite gun video clips. I don't want to inundate the system with questionable and conflicting codecs, so how should I go about doing this? In the past, I only loaded Divx and Xvid which seems to solve 90% of the problem, but not always. What other codec packs (god forbid) should I consider - ffdshow, etc.? I know about G-spot but that program doesn't always help.
