Windows 10 Avi-file video (not audio!) playback issues

So, I recently updated to Windows 10 - partially feel like that was a mistake now, but oh well. Most of the issues I have with it are just connected to it having different design than windows 7, and me being overly used to Win 7, so I guess it'll wear off.

There is, however, one severe problem I noticed when trying to play back some AVI files of CoD gameplay I had stored on an external harddrive. They played in Windows Media Player, but showed no video; in fact, it instead showed the musical note that is characteristic for when you play back files in WMB that are audio only. However, the audio from the AVI file still played. I know for a fact that the files aren't corrupt or so because they are playable on another computer of mine which runs on Windows 7, and they used to work just fine on this computer too before I installed Windows 10, *at least as far as I remember.*

And it's not just in WMP you only get the audio. Also when importing the files into Vegas pro 12 and After Effects CS6 I get a black video preview that only plays back audio.

And here comes the final crux: it's just some AVI files that you can't see the video of. After some testing and thinking I figured out that the files i couldn't play were AVI files recorded with Fraps, and the playable ones were recorded with Dxtory.

I'd love some thoughts on this if anyone has ideas, and if you want more info on some area in order to maybe understand what the problem might be, just tell me. Anything to get help! >.<

I have very very little understandings on this subject.
Just a suggestion :
Have you tried using VLC Player instead ?

Sounds like a codec problem. I agree with davidhk, try VLC or MPC-HC.

It works, on the VLC player, for whatever reason. Awfully strange considering it doesn't work on neither Vegas 12 nor CS6 AE on this computer, whilst it works on those two programs on my other computer.

Thanks for the tip - now I can at least preview the footage on this computer. Yet, I really want to be able to work with it in AE and preferably also in Vegas since, well, otherwise I can't do much with the footage ;^)

So I don't check solved just yet...

VLC has been widely used and highly recommended.
The strong point of VLC is that it is capable to play almost any file formats without installing more codecs, unlike WMP which requires certain file formats or no go.
That's huge.

Yeah, indeed... The strange part is that I thought CS6 and Vegas worked the same way regardless of what computer they were running on, at least regarding which files they can play back. If a file works on the programs on one computer, it works on those programs on any computer, is what I thought.

But that doesn't seem to be the case here.

Correction: trying to import the files into Vegas 12 an error message pops up in Vegas saying "None of the files imported could be opened", one cannot even get the file into Vegas as opposed to what i said earlier...

Bumping this since I figure some people might've been sleeping by the time this thread was posted and now it's pretty far down the lists.

Not neccessarily true. VLC uses its own built in codecs (LIBVLC.DLL, LIBVLCCORE.DLL) to avoid any conflict with any other codec packs installed in your PC. Sounds like you'd need to install a codec pack to work with other software.
Try: Download K-Lite Codec Pack

NOTE:Create a restore point before installing any codec packs just in case you want to undo.

FYI, For any VLC users. From the link above, there's 32 bit version including both Installer and portable (No installation required).

The only version that came with 64 bit is the installer. Since I love portable software and to make it portable with 64bit, just use 7-zip to extract to a folder then use it as portable.

I found a solution to this problem in the Windows 7 forum which worked just fine on Windows 10 system.

Can now play my AVI files with audio AND video.
