@leoliver
go on with the simple project (one small clip - no menu). To reduce unknown variables, be sure that the small clip has a "standard" name and path (i.e. c:\movies\clip.avi), the output folder has a "standard" path (i.e. c:\movies) and if you save the project, its pathname is "standard" as well (i.e. c:\movies\project.a2d).
After pressing START, do you get the project summary message window (like
this)?
It should not have an impact to this particular issue, but, I have taken a look to the attached codecs list and it is amazing! You really have hundreds of them! Do you really need them all? For 99% of application ffdshow should be enough.
