Due to an initial unawareness of the dangers of
installing codec packs, such as K-Lite/Nimo, I ended up
with a situation where on uninstallation of such codec
packs (to remove excess codecs), some were left behind.

Further attempts to selectively remove these persistent
codecs (of which Xvid was one), proved futile as 'Control
Panel\Sounds, Speech and Audio Devices\Hardware\Codec
properties' did not allow me to remove them. On removal,
they returned upon a refresh. Removal whilst in safe mode
also did not work.

These codecs, along with other missing codecs (as
reported by Gspot), continued to plague the playback of
certain video formats and reinstallation and subsequent
uninstallation of codecs (from packs) as a remedy proved
unsuccessful. Direct searches for their registry keys and
deleting from there also didn't work, as they continued
to be reported by Gspot and presumably continued to
disrupt Windows Media Player.

The knowledgebase on MSDN provided no useful results, as
there is no mention of how to remove codecs that persist.
Reinstallation of DirectX (by upgrading to 9c from 9b)
also proved unsuccessful, as the codecs could still not
be removed. Similarly, attempts to unregister them via
regsvr32 proved unsuccessful as it claims some the the
corresponding .dlls have no entry points for
registering/unregistering.

I'm aware that some of these codecs (actually, the
majority) are directshow codecs and these are most likely
the culprits for WMP playback problems.

Has anyone else had these problems? Does anyone have a
solution other than formatting proceeded by a clean
install? Is there a way to unregister all directshow
codecs? Is there a registry repository for these, that
allows simple removal? I would be grateful for any help.

Download the free Zoom Player Standard. It allows viewing of the filters.
You can change the merit numbers on video decoders or unregister them as
desired.
