why are video editors so problematic

Downloaded Nero 9 to try out Nero Vision. For one of my files with all the video from Munich, Nero was only showing 2 photos available and no video. I know the video is ok, since it worked in Pinnacle. For one of the other VOB files, when I dragged it to the timeline, it split it up into a bunch of separate parts, and I don't see any option to change it not to do that. Even worse, when you try to preview the video, it stops at the end of each small part, instead of playing the whole thing.
Another thing I tried was using the "Recode" to import a VOB file as mp3 files, but that also split it into 130 individual small files!

So then I tried Sony Vegas Movie Studio. Editing the video was more complicated than I was hoping for. The program had various annoyances; not doing things the way I expected.

So then I tried Ulead. Apparently Corel owns them now. Corel Video Studio 12. It doesn't have all the nice video effects I remember from the last time I tried the Ulead trial version (which kept crashing on me, on my other computer)(actually, maybe it does still have the effects; they're just a bit harder to find). I was able to import my videos and edit them and add titles. But when I go to create the DVD from them, it crashes while trying to add chapters. The DVD menu creation options are also very limited and not what I want (it doesn't have what Pinnacle has).

Windows Movie Maker doesn't recognize my file format (DVD files - the vidcam writes to mini-DVDs). I'd have to convert the files first, which might result in loss of quality or other problems.

So, now what? I can try the Sony Vegas program some more, I guess.

Or create a 54 minute long DVD with no menu or chapters.

Or start over in Pinnacle and hope that it doesn't mess up the audio again.
