My DVD Architect is no longer accepting .m2v files rendered in Sony Vegas. In Vegas, I am clicking 'make movie...' and then select 'blu ray with menus'. When the video file and audio file are done rendering, I click 'send to DVD Architect'. When DVD Architect opens, the application hangs on 'processing command line'. When I try to manually insert the .m2v file that Vegas rendered into DVD Architect, the program hangs at 'opening 0%'.
This process used to work fine, so I am not sure what could have caused the issue. I am using Movie Studio Platinum 13 and DVD Architect 5.
I had a similar problem but found that instead of opening or importing the file I simply previewed it first. It previewed fine and then I was able to open it in the normal way.
For me it was any m2v file created from vegas - regardless of size.
