Codecs and Windows Media Player 9
I have some video files I have downloaded off the net and whenever I
play them I get the error: "An operation failed due to a certification
failure" however, these files show a preview image. My thoughts are
that I have the right codec, or a codec that is similar enough to make
the preview image, but for some reason, it won't play. I tried other
players like PowerDVD XP and even renamed the files to a different
extension (like .avi to .mpg). Is there a way to get Media Player to
try more codecs if the first one fails, or a program that tells you
what codec a particular video file needs to see if it is available. Or
am I taking the wrong road, is there something else that could correct
First off you have not specified what kind of media are you trying to
open..eg.. AVI or MPEG-4 or xVID. But I have come across simmilar
problem. The best solution will be to goto www.divx.com and
download/install the CODECS... also try using the DIVX player that is
available there... I believe it plays virtually all media type files.
Hopefully this should resolve the situation. Let me know how it goes... cheers.
Codecs from Microsoft here
If you got this video file from file sharing (Kazaa etc) you most
likely have a fake
and nothing will make it work because it's not an actual video file
it's just a large
file renamed to a video file extention.
I've had various problems with codec. Downloading and installing this
resolved almost all of my problems:
Here's a previously asked question concerning your same error message
where the following answer was given:
Make sure you have all the WMP updates from the Windows Update site.
This may be a codec issue. Depending on the type of file, you'll
either want the DivX codec (which works remarkably well), or the Nimo
Nimo codec: http://www.divx-digest.com/software/nimo_pack.html
DivX codec: http://www.divx.com/divx/?src=toptab_divx_from_/index.php
(click the Standard DivX Codec FREE link)
FYI... the k-lite codec include all of the codecs that I'v tried, such
as DivX, Intel, etc.
Ok, thanks for all your help so far. Here is what I have:
WMP9 is fully updated
I installed the latest codec pack that MS offers
I already have installed on my system the latest divx and xvid codecs
as well as many others offered in the ACE mega codec packs
I am hesitant to install the Nimo codec pack and klite codec pack as I
have been reading that they contain many viruses and spyware
I am trying to play video of mpg, avi, asf, mpeg2
I hope that answers all questions
If it comes down to it, I will try the klite codec pack, however, is
there some program that will tell you what codec you need to play
video? that way i would only have to install those codecs that are
Don't throw in those weirdo codecs.
Identify the codec the clip was compressed with. USe AVIcodec for
this. It's free and it's a right-mouse click on the file to show info.
Great little proggy.
Thanks spiderfix, that was just what I was looking for, interestingly
enough, the program says that all the video files I cant open are
Windows Media Video V7 or V8, but I have both installed, perhaps they
are corrupted or something
Perhaps not. I would venture to say that unless you downloaded these clips from
a large commercial site then it's probably some hobbyist computer person who
didn't make the clip properly. If your looking at a black screen in WMP when the
clip plays and a error pops up right away then this is probably where you stand.
>>"An operation failed due to a certification failure"<<
>>the video files I cant open are Windows Media Video V7 or V8<<
Only hobbyists compress with WMP. Pros use specific software designed
for such a purpose. WMP is freebee WindowsXX software and the last place
a vid-person would compress a video.
