Looking round other video forums it looks like you are going to have to recode the video files - despite the codecs being installed it would appear that many other video editors also cannot handle this file format
I would ask why are you using a relatively obscure video format and what is being used to create the video file?

I do retro pc game reviews. That's the format DosBox natively captures video in. The files are very compact while retaining the detail and high frame rate. Recoding the files would result in additional artifacting, larger file sizes and loss of a variable frame rate. The only alternative I see is just using uncompressed video, but I use a rather old machine to edit, so I don't think I can handle a lot of huge video files.
That is what I suspected you were using and the reason why, this results in a Catch 22 situation.
The ZMBV is not have a particularly good compression ratio compared to more modern codecs eg H.264 and can produce quite large file because of its lossless video and uncompressed audio which in itself will cause problems with PC.
H.264 is by far the best of the compressed formats for compact files while retaining high quality - the downside is that they require a reasonably powerful PC to edit smoothly.
I'm aware of most of them. However, like I said, my machine is not very powerful, so being able to record at full speed and small size is what I'm looking for. DosBox dumps out files at the exact rate the frames are rendered, so I can have a game run at 5 fps, while the resulting video is at 60 fps.
What really bums me out is that it worked just fine with the previous version of MEP.

Okay, so I figured out the settings for ffmpeg that fit my need and can now produce beautiful h264 files with crisp detail, great framerate and all that.
BUT the new issue is those files won't load in MEP properly! I get a black screen and no audio!

What are the settings you are using?.
It will help us users help you if, when you find something that gives a second problem having fixed the first part, you give a detailed explanation of for example the settings which got you what you need, but cause a problem in MEP.
It saves us asking the obvious, and the frustration of you having to answer further questions to get more information for which we may have an answer immediately - not always guaranteed but more information is better then less helps get to a hopefully successful solution for you quicker.
