My MSN ID is my email address, so 
I’ve had this annoying popup for ages. When you highlight an AVI file and hold SHIFT it often appears. This is most annoying when you want to move files (SHIFT+mouse) or force-delete (SHIFT-DEL).
I did some digging online and the best solutions I got were pointing me to a settings or configuration program within some XVid codec installs. Thing is, I don’t have those particular codecs so that didn’t help.
A bit of a dig later, courtesy of Process Explorer (formerly by sysinternals, now Microsoft) and I found that the program being used was one avisplitter.ax which can be found in C:/Windows/System32. I renames this (popped a “.bak” on the end)… and problem solved.
As far as I can tell, this has had no other effects on the system. Everything else seems to be working fine. However, I’ll leave the file in place rather than delete it just in case.

Well done. The simplest fix I have found and it worked for me – Thanks
You’re welcome – happy to help!
The reason why it pops up is to inform you that something is wrong with the AVI file.
Just by disabling the viewer file, it won’t solve the problem (the index of the AVI file is corrupt, or the video and audio tracks are out of sinc, etc.
1. Get VirtualDub (current version is 1.9.9).
2. Unzip the file into an empty folder.
3. Launch VirtualDub.exe.
4. Change the settings… in the Video AND Audio tabs, set EACH to Direct Stream Copy
5. Open the AVI file (File… Open Video File) you’ll see a warning window that tells you
about the size of the possible problem. Just close it.
6. Save (File… Save as AVI) to a different folder than the one with the problem.
Watch the new file… if the AVI Chunck Viewer warning does not show up… the problem is fixed and you can delete the original file.
Hope this helps you.
Hey PS. That’s another possible solution to the problem, but the Chunk Viewer doesn’t only pop up for “damaged” AVIs. It was popping up for every single one I had on my PC, regardless of whether they were downloaded, created fresh or converted from another format. It was simply annoying! By deleting one of the files it needed to run, I managed to stop it which is all I was bothered about
It should only show up when damage is present, after all that is the purpose of the program. The blue and red lines should run almost one on top of the other, representing the video and audio are in sinc. Any deviation = damage… shown as separate lines.
I don’t get the reasoning behind deleting Chunk Viewer and keeping corrupted files, instead of spending 2 minutes and fixing a 700Mb file. Sounds a bit like when getting a virus, instead of attacking and eliminating the virus, the antivirus is deleted so the warning of the virus attack won’t show up again.
My reasoning for deleting it was that almost every time I tried to move files (by holding SHIFT and dragging them) this flipping thing popped up, unwanted, and got in the way. I didn’t deliberately install it, I’ve no idea what package I have installed which did it for me and there’s no option to *not* have it any more. No uninstall, no “off” button, nothing.
I also don’t believe that almost 100% off my AVIs had problems. Certainly, I’ve watched most of them and there are no visible or audible issues as far as I can tell. So whatever “faults” it was trying to tell me about aren’t worth the hassle.
Essentially, it was useless, annoying and shouldn’t have been installed in the first place.
Use the tool CodecTweakTool_422.exe from K-Lite.
Than: Manage preferred source filters abd set AVI to Microsoft (default)
Greetings
I get so sick of listening to the people who mention VirtualDub and say that AVI Chunck Viewer is just doing its job and has detected a bad or corrupted avi file. That is bullshit. This stupid program has never detected a bad file, it just comes up when you press the shift key.ewer
I think i have solved this: the program is installed with FormatFactory. After reading this article, i searched my computer for the file AviSplitter
I found it here: C:\Program Files\FreeTime\FormatFactory\FFModules\Filters\AviSplitter.ax
After renaming the file, i can hold down shift while clicking an avi file, and no longer see the AVI Chuck Viewer come up
OK, two comments by two “different” people from the same IP address on the same old post, but I’ll let it slide as the blog doesn’t get so muc traffic these days. Do note that I think the Chunk Viewer is installed “inside” a *lot* of different software packages. It’s just hard to figure out which one you have on your machine.
I was in the same situation – no new codecs, changed nothing in my system – and it popped up every time I used shift in Word. Extremely annoying, great solution.
Thanks!
Just another idea for those using Format Factory, in the advanced section of Options, uninstall all “inside codecs” then go to Program Files\FreeTime\FormatFactory\FFModules\Filters and remove or delete avisplitter.ax. Now simply go back to Format Factory and re-install the codecs.
Its not perfect, but hey, what is?!?
If it works, it works! That’s great, thank you
And no worries on the “fake.email”. Helps prove you’re not a spammer!

Thanks – AVI Chunk Viewer must have arrived in Format Factory. Adding .bak to C:\Program Files\FreeTime\FormatFactory\FFModules\Filters\AviSplitter.ax did the job.
Thanks, Rob. Yes, renaming a file is always a better alternative than straight deleting it. Just wish they’d stop tagging the program onto the installation of so many other applications.
Thank you Mosh & Rob. I found it to be in Format factory.
I also found out it will not pop up if you wait a second after clicking on the AVI file before hitting the shift key.
I’m using Vista Home Premium
The now infamous AVI Chunk Viewer pops up EVEN THOUGH i don’t press the SHIFT key on my computer keyboard.
It is obviously a video utility someone wrote to alert AVI video format users that the video/audio file is not saved perfectly interleaved. People get annoyed by this popping up and therefore delete, rename or somehow neutralize the AVI Chunk Viewer.
But the utility simply warns you that were you to copy the AVI video, as is, onto a DVD drive, it might not play well on a “slow media, like a CD-ROM”. On the hard drive it might not matter, and yet could be the reason for some slight video-audio out of synchronization.
I get this AVI Chunk Viewer pop-up ONLY with AVI files exported from CAKEWALK. It obviously writes the file in such a way that chunks of video data are given priority over audio data, at the beginning of the file, because there’s a lot more video data per frame than audio data. I think that’s a clever way to write the video file, but AVI Chunk Viewer gives an alert based on other assumptions as to how a video/audio file should be written to Disk.
Though the pop-up warning is triggered with CAKEWALK exported videos, the videos play from my Hard Drive with perfect synchronicity, but if I try to trim/edit those videos, (freeware) software I’ve tried jam up, or say “video will have no audio”, or some other problem. I just don’t think the makers of the freeware are cognizant of better concepts as to how an AVI video is best written to Disk.
AVI video is ancient and has many variants, so it is no wonder some, more modern, software cannot deal with all the variants. But it is a loss-less format, and I like it for the crispness of the video component.
Hey there. Found a few other instances of the avisplitter.ax file on my machine. Thought you may want to know it also seems to be packaged with WinAvi Video Converter, The KMPlayer, and K-Lite Codec Pack. The .bak trick mentioned above worked just fine.
Thanks Justin, and Little Man. Says something when this post is, I think, the third most popular of all time on my blog!
Thank you Mosh.
Most annoying spamware ever.
I don’t care in any kind of way about the information this program is giving me. I couldn’t care less if anything is wrong with my avi files. THEY WORK!!!!!!!!!!!!!!!!!!!! Whatever problem they might have, have absolutely no effect, and therefore have absolutely zero relevance. Hence, this program is a piece of crapware, that made it’s way onto countless peoples computers without them wanting it to.
Whoever decided to include this crapware with whatever software made a HUGE mistake.
I don’t want this crap on my computer. It has no use. Drop it!!!!
Do not be telling me or others complaining about it, how to fix their avi files. It has no relevanse. Just stop this crapware now!
Well, it pops up WITHOUT me hitting the Shift key, without using ANY avi-files at all, and – the most funny part! – I don’t even have that AviSplitter.ax on my PC! I have no FreeTime\FormatFactory or whatever of the above-mentioned directories either… How on earth could I remove/rename a file that I don’t have?… Any suggestions – anyone?…
Found it on \Windows\System32
. I have just renamed it to .bak. Also found a avisplitter.ini on /Windows. Hope it works!
[...] AVI Chunk Viewer: how to remove it [...]
In windows directory, look for AVI Splitter.ini
Change the line to read: HideAviSplitterWarning=1
If that works, it’s a nice little solution! Still, it would be even nicer if this package wasn’t installed without your knowledge in the first place.
