Yes, that seems to be the case. The error AVC it gives me seems linked to Microsoft Visual C++ Redistributable, so it might be something to do with that. If it's something to do with my programs then I don't know which one it could be, because I have barely any installed at the moment.
On a partially related note, I found that all my MKV files, and the MP4 files that I converted them into, had very bad artefacts when they were played in any media player as well as when I rendered them in Sony Vegas, but not while I was actively editing/playing them in Vegas. I uninstalled my codecs and now they play fine, but unfortunately some of my footage is in some kind of h264-related AVI format (I think, I'm not good with stuff like that) that Vegas doesn't like, and as it turns out the video conversion issue is not exclusive to MKV files, but all file types, so I can't convert them to fix the issue.
