Avi chunk viewer?- what is this?!

I suppose you have already heard about this

I tried to play some of my avi DivX files that I ussually watch in Windows Media Player and suddenly I get a message from some strange program that I HAVE NEVER SEEN BEFORE "Avi Chunk viewer" :
"This AVI file was not prepared for sequential reading, the alternative 'AVI Splitter' will now let the default one handle it. The complete reinterleaving of this file is strongly recommended before burning it onto a slow media like cd-rom"

Can someone tell me please where the hell this software (SPYWARE?!) came from? I dont want it and I didnt installed it (AT LEAST not by my free will)! I suppose it installed itself with some other programs (I dont know where it may came from, last programs that i remember that I installed are: Pegasus MJPEG encoder, Main Concept MPEG encoder and maybe 1-2 other)
Previously all those files could be played without any problems at all until this thing started to annoy me.

I tried to Google on this problem, I can't find any detailed and clear information where this thing comes from, is it an adware, does it do any damage etc. I only found some opinions that this program was sort of useful (?!) cause it helps playing corrupted files (then how come I could play all those files until recently without absolutely NO problem)

Thank you very much in advance for every detailed info how to get rid of this

I found a screenshot too :

Yes, I've seen that message. It is normal, it isn't spyware. You're being warned that your Divx file isn't indexed properly. Download this little script and run the Lossless_Gain.bat file on your AVI. It won't touch the original file. The batch file will re-index your AVI and it should work smoothly.

thank u for ur quick reply, but how come i've never seen this avi chunk viewer before? As I pointed out I have watched these same video files with Windows Media Player, Winamp etc. milions of times before with absolutely NO PROBLEMS...until today. They are not corrupted in any way, I have watched them on my computer, in dvd player etc.
I dont want it. I would like to know does it change/damage my files in any way, how can i get rid of it and how I got it, with what program?

Thank you, I would aprecciate any further info

Something changed.... You can search for files that have been copied to your system in the past few days, but the indexing issue happens every once in a while. Hey, here's a simpler batch file for you to try.

Make sure your AVI has NO spaces in it

Bad: This Is My.AVI
Good: This_Is_My.AVI

copy AVI into same folder as Reindex.bat and double click Reindex to run. New files will be named
Indexed-original_file_name.avi

As far as WHY this happened... So many possibilities. Usually minor errors. When you can, run Chkdsk on your hard drive.

Soopafresh, thank you very much for trying but unfortunatelly its obvious that we dont understand each other.

I dont want any scripts, i dont want no "reindex.bat", i dont want to do anything with my files, there was absolutely nothing wrong with them. I've watched them humndreds of times with absolutely no problems until YESTERDAY (straight from hdd or burned on cd/dvd in a dvd player, everything was fine). even if something did happen meanwhile with the hdd which corrupted my files as you would suggest please have in mind that I never wanted to install this "Avi Chunk Viewer" program so i have right to call it "Adware" or "Spyware" and an "unwanted present" (probably came with some other program). I DONT WANT IT, I HATE IT, even if its helpful (which i doubt)

I want to get rid of it, I have every right to know how it came here (not to install it again by mystake) and most important of all did this program process my files in any way or it just analyzes them to find "errors"?!

Have you installed any programs recently? Updated any software? Any audio/video program may have installed a different AVI splitter or codecs that caused this. Media Player Classic maybe?

vanjo, my pleasure for the Reindexer.

Very, VERY difficult to find the problem unless you run a program that monitors a system for changes. It is too late to do that now.

You can run WhatChanged http://www.portablefreeware.com/?q=whatchanged&m=Search
Then, the next time you have such a problem, run Whatchanged again to see the changes to your system since the first time you ran WhatChanged.

Maybe you installed this with some codec pack or media player:

Use something like FilMerit or Radlight FilterManager to remove it. Don't remove the one that's par of Quartz.dll.

seems that I got rid of it! (at least i hope i did and I also hope there will be no consequences or damage from it)
i just uninstalled Avi2DVD (which i have installed recently along with other programs), I tried to play those same files with Windows Media Player and that annoying "Avi Chunk Viewer" is gone.
The files play well, no errors or anything, just like they did in the past. I also checked the properties of those files and there are no recent modifications reported (I still worry a bit, dunno why)

After the uninstall, i still have AVI2DVD folder with some subfolders:
Avi2Dvd\Programs\Filters\Haali media splitter

Inside it there are two dll's. I hope I can delete this manualy without further problems, I'll try.

Just to add that I did the unistall in Safe Mode (dunno if it makes any difference)

Hope this solved the problem for good. If not, I'll post here again.

I do not know if my problem is related but here goes:

Today, a few weeks after I got rid of this avichunk viewer, I got into problems when opening a folder with avis in it. Explorer just crashed all the time saying a file called "mpeg2dmx.ax" was causing it. I Found that this was related to WinAvi software by ZJMEDIA ( http://www.winavi.com/en/index.htm ) and I suspect that this was also the software that installed avichunk viewer. I then just resolved the issue by renaming the file "mpeg2dmx.old" and now it looks like it is working, no more crashes.

I found what appears to be a fix to get rid of that annoying AVI Chunk Viewer, which appears to come up with certian AVI files when you have the "AVI Splitter" installed. For me, it was installed with the K-Lite codec pack, and can be disabled without uninstalling K-Lite, just use their "Codec Tweak Tool" located under your Start menu's
K-Lite Codec Pack\Configuration\ folder. Scroll down until you see AVI Splitter under 'disable...' section, and check it off (be sure to uncheck the rest that automatically get toggled on when you click AVI Splitter), and that seems to have done it for me (although i have only tested a few files, but they used to make the AVI Chunk Viewer window appear, and no longer do).

Hope this helps.

Thanks to the one who answered for this tip and for the one who gave the Codec Twek Tool tip. It did work for me just fine.
Thanks to other contributions too, audio normalizer and other scripts you talk about turned very usefull too, didn't know they existed.

Cheers. See you arround.
