Nel frattempo ho fatto altre prove. ed il WD non sembra riconoscere il tipo di codifica del filmato. Per quelli che funzionano mi dice "H264", per quello che non funziona mi dice "unknown".
Comunque ho già provato ad usare proprio MediaInfo, ma non sono abbastanza pratico da comprendere le differenze...
Se hai tempo, prova a dare un'occhiata:
