My post is a little confusing. I think that you are not understanding what I am saying.
I'm not talking about the slow movement when I am playing the online match real-time (in the present -- the opponent and I are connected over the Internet and playing each other). I am referring to the playback of the match from the .dmo file (the opponent and I have disconnected and I am watching the match).
OK. So, the issue is that when the .dmo file is played normally (say if the .ini file is edited with the name of the .dmo file, the game is launched, and the Warm-up option is clicked), the playback seems to show what happened during the actual match. Now, in the actual match there was slowing of movement, skipped frames, and such, and these can also be seen in the playback of the .dmo file when it is playing normally. That is not the issue.
However, if during the normal playback of the .dmo file the F1 key is pressed and action is replayed, the skipped frames and slowing of movement are taken out for the most part. So, when the action is played normally from the .dmo file, you see one thing; when the action is replayed from the .dmo file (using "Replay") at normal speed (as you have normal, half, quarter, etc., speed), you see another. That is the issue.
