I have run codecmanager and it says I have old versions of FFDShow and MPEG 2, it seems to download the latest versions, but codecmanager continues to report them being out of date, so I then updated ffdshow manually as well I did the AC3 install manually although I received no AC3 errors. I did not update any MPEG codecs.

Codec manager still reports a couple older codecs (including MPEG2), but wont let me uninstall or update them (doesn't work from within codecmanager at least, which is why I updated FFD and AC3 off net).

Where in the filters advanced menu am I supposed to be looking for usable information?
