This resulted in the whole file being converted, just as if I didn't enter anything. When you say "the whole file being converted", what exactly do you mean? Did the resulting DCP play back the whole source file, with no trimming? Yes, exactly that. As Carsten was asking how I tested the results, by the way: I'm using "Stereoscopic Player" to play the DCP packages. On the subject of the trimming method - do I understand this correctly: Does "encode all frames and play the subset" make a package of the whole film and writes instructions into the metadata to only play the untrimmed part? Or what does it mean exactly?

For my second try, I entered the number of frames I wanted to cut from the beginning and the end of the video and selected "encode only the subset". Now, the *audio* was cut at the right point, but the video played from the beginning again. I think that is due to a bug in DVD-o-matic which will be fixed in the next version.  You can work around it by deleting the "video" folder within the film's folder before creating the DCP.  DVD-o-matic mistakenly tries to re-use the old video content (with no-trim) but creates new audio. Ah, that might be it - I didn't erase the old video dir in the "project" directory. I will retry that later tonight and get back to you on that.

Additionally, I saved the project and loaded it at a later time. Now, the "Start" and "End" fields were set to "100" each, which bears no resemblance to what I had input into the fields before saving (750 and 251, respectively). That is strange.  Is that repeatable? Yes, it seems to happen every time. I just did the following: 1. I created a new project named "BLUBB". 2. In the film tab, I loaded a dummy Quicktime movie (in this case, a 1080p film trailer from apple.com which I had lying around), and waited for DVDom to analyze the file. 3. Then, I entered "500" in both the "Start" and "End" fields next to "Trim frames". 4. I selected "File"->"Save" to save the project. 5. I exited DVDom. 6. I started DVDom again and reloaded the project via "File"->"Open". 7. Now, both fields contain the value "100".

I just remembered an important detail I forgot to mention with my first try. I didn't generate the DCP right away, but rather saved the project and loaded it later into your shiny new batch encode tool. If the trim values aren't saved correctly, then it's no wonder that the first try played the untrimmed video - the fields probably were reset to "100", too (which you can't see in the batch encoder, as the values aren't displayed).
