Thanks exTermia for this submission.

Microsoft have issued a fix for Windows Media Player 9 & 10 that fixes color smearing or a bleeding effect when you play MPEG4 videos.

According to the knowledge base article at Microsoft, this is caused by the MPEG4 codec, sometimes using invalid motion vectors.
    SYMPTOMS
    In Microsoft Windows Media Player 9 or 10, you may experience a color smearing or bleeding effect when you play some MPEG4 videos. This behavior often occurs when the video contains fast-moving scenes of varying colors.

    CAUSE
    This problem occurs because of an issue with the way that the MPEG4 codec handles motion vectors. Sometimes, the decoder mistakenly uses invalid motion vectors.

what's still bugging me is how all newly encoded XVID .avi's are playing fine on my monitor, but don't display on my tv. It's weird because I can have the video windowed, and see everything else that'n on my monitor on the tv, but the video that's playing is just black. ANybody know a fix for this?
#4.1 iZian on 03 May 2005 - 14:51
The black over the film is put in there I think by the graphics card provider, possibly in conjunction with the operating system, to stop the public viewing of DVD and other video media.
I have got round this by fiddling with the resolution while videeo is playing and sometimes it fools it into playing on the external screen, it's the same for projectors.
#4.2 MR_Candyman on 03 May 2005 - 15:06
but it only does this with the newest xvid encoded files...everything else works flawlessly. I would have thought if that were the case barely any of my other videos would work correctly. It's not like it's a new card either. It's a ATI radeon 9800 pro. Workes flawlessly for every file but the NEWEST xvid encoded ones (older versions work just fine)

hmm...odd...I just tried setting my tv as the primary output and it works on the tv now and not the monitor. Must be a security feature

U can fix the above problem.by turning of hardware acceleration in display properties
#4.4 MR_Candyman on 03 May 2005 - 15:17
thanks, setting it to disable directdraw and direct3d accelerations works, thanks guys

It's known as an "overlay" - unless your TV is the primary monitor, it won't display it.

what is the best mp4 decoder for wmp10 ?
#5.1 Express on 03 May 2005 - 19:40
xvid is good.

divx is good too but I hate the fact that it tries to install toolbar and other crap and send your system information to their servers when you install it.

nero codec is the most advanced with support for H.264 main profile. But it is limited to only play videos which are encoded using Nero.

ffdshow hasn't been updated in a while. It provides great quality with very low CPU usage. Also it has tons of options to tinker.
#5.2 Tom Servo on 03 May 2005 - 20:38
Uh, I've played all sort of Xvid and Divx files on WMP using the Nero codec, all just fine. It also plays the H.264 test files I've done with x264.
#5.3 Express on 03 May 2005 - 21:45
Which container are you using to get Nero codec to work? Does it do avi ? I am unable to get avis to work.
#6 jkolonko on 03 May 2005 - 18:32
What's the point of adding "Check for updates" to WMP if this function always says "You are running the newest version, go away." even if there really are updates like this one
#7 Jugalator on 03 May 2005 - 19:02
Good to see a fix for this, but why the hell do they need to take a lot of time to translate it? It's only available in english and japanese right now? First, why need localized versions at all for a bug fix to an algorithm? Second, why does it take so much time? It's not like they're translating a book. I'd have an easier time understanding localized delays for WMP 10 itself, but this is an algorithm bug fix against smearing, nothing more.

Excellent work!

WMP is still choppy when playing hi-res xvid movies, even WITHOUT post-processing (deblocking, sharpening, etc). I get no choppiness from the same movie in Zoom Player or Media Player Classic WITH post-processing running. That's rather pathetic performance by WMP, wouldn't you say?
#9.1 miniM3 on 03 May 2005 - 21:03
Well, there are other players around if WMP doesn't satisfy your needs....

I get the same problem. My video is running perfectly fine for a while then bam! It goes all choppy out of nowhere and I have to exit WMP and get back into it. Funny how I never ever got any choppiness on WMP 9.

Isn't 10.00.00.3802 the latest version? why is it that when i check for updates on the player, it says an update is available and the update is the same version?
#11.1 Dirtie on 04 May 2005 - 00:32
Well for some reason mine is build 3646, and it says it's fully updated...
#11.2 JOEWARE on 04 May 2005 - 01:13
