I'm really confused now. Your profile works perfectly. However, when I recreate it manually on my system, it doesn't work. The attached is, I believe, essentially the same as yours (my target context is OutputFile instead of CutDVRMS). The logs are different, too. However, if I create a profile that is identical to yours, it works.

Thanks again for taking a look at this.
