Good evening,
First deception : I tried DVD Architect Studio 5.0 (trial version) and the .m4v files creatd with AME are not recognized.
If you nave a glance in the summary of this software : no list of files format.
PP CC gives sequences that are encoded with AME, but these encoded sequences cannot be used with DVD Architect Studio.
Next step : trial with DVD Architect Studio Pro 6.0 (about 200 USD) instead of DVd Architect Studio 5.0 (about 30 USD), Encore : free (no cost).
