Don't install "some codecs". Install only those you think you need from
reputable sources.
There are many video formats, and WMP10 will play some without 3rd
party codecs, Quicktime will play others. You need to slow down,
uninstall any codecs or codec-packs you have already installed, reset
the file assosiations of WMP and QT to their defaults and start again.
Then when you cannot play a video file, go and find a proper codec for
it that is compatible with WMP, from a trustworthy source. Check with
Microsoft site which ones are known to be compatible.
You sound like you've just thrown a load of random programs into your
system and hoped for the best.
