So, after having installed new mods and gone about merging them as directed, and deciding to test them out, I naturally get a bazillion errors for me to tear my hair out over. Symptoms include abnormal loading times, the intro movie not loading up, and the game locking up for a minute or two before working again.

Now, here is what errors I got in my warnings file:

So, what seems to be the problem here?

You need Westly's Master Headpack resources. Also, I don't think you want Undead.esm with that version of MCA you are using. That won't fix all those problems you are talking about though. Honestly it just looks like you need to be more careful installing mods in general. Does the intro movie still crash without mods? That sounds more like a codec problem or some other system issue.

I wasn't sure about the Undead, but I've since installed the head pack after a bit of research. Future tests show the movies working, but the whole thing still stutters from time to time, most notably when the animation for the title screen and main menu loads up.

I wouldn't worry to much unless your gameplay is stuttering or crashing. Those movies are loaded from the cdrom unless you drag them from the disk so they could be loading slow. Is your game smooth now?

Smooth as it can get with Distant Land running, yeah. The loading times are just longer than they usually are.
