Vista/WMP11 MPEG-1 (50) Missing Codec Problem

Sponsored Links

I just got Vista Home Premium and went to download files that I had no
problem doing with XP and I get:

"Windows Media Player cannot play the file (or cannot play either the
audio or video portion of the file) because the Microsoft MPEG-1 (50)
codec is not installed on your computer".

I've checked a few forums and evidently this is a wideapread problem
without a solution other than using another media player which I don't
want to have to do. Why is this even a problem since all are MS products
and Vista has been in release for some time now?

Does anyone have a fix other than my using Winamp? :(

GOM player?

Sorry, I don't understand your reply "GOM player?" :confused:

That indicates that something likely stomped on the system's MPEG decoder.

What is listed under WMP's Help:about:Technical Support Information menu
tool's "DVD/MPEG filters" list?

please inform me as to wat i'm missing/need to do

I have no idea what you're replying to.

You have a number of MPEG filters installed - I can't imagine a good reason
for that. I would suggest only installing codecs you specifically need.
Since you've got a ton of filters here that are going to conflict with each
other, that sounds like the source of your problem. I would suggest
figuring out what installed those why, and removing whatever is installing
five redundant sets of codecs to your system.

Did anyone ever find a solutions to this problem, becasue I am having it
too. Files that played fine on XP now won't play in Vista. I don't want
to switch media players, and renaming the file is not a solution. I have
Vista hom Premium. I don't under stand any of the technical threads I've
read all over the web. The replies in this thread also make no sense as
I believe they are copies from other forums. Does anyone have a solution
to this? I have tried downloading Vista Codecs Pack and that did not fix
the problem.

If anyone has a proper solution that will allow me to run media player
without renaming the files please let me know by replying here (local to
this forum, mirrored and copied posts from other forums (such as in
above posts) gets VERY confusing and causes a ALOT of unessecary jumping
around). I'd appreciate it. Thanks

I'm the guy who made the original post. Though it has been awhile since
I posted, if I remember correctly, it was K-Lite Codec Pack that did the
trick for me. Google it and check it out. I hope it works for you.

i want that software

I have had no problem with this in the past on Vista and now I do. How
do I fix it?

why dont you use vista codes , it is very useful and it is free , you could
download it in this website
