Digital Copy M4V not playing in 5.1

I have a few digital copies that came with my bluray. I am able to rip them and play them with no problem using nitotv. But using Sapphire it plays in stereo and not 5.1? Any ideas? Thank you.

Sapphire has a separate setting for 5.1 sound. Make sure the ‘AC3 Passthrough’ option is checked in Sapphire’s Settings menu.

It is. Same thing.

I am still having the same issue here? I have made sure that it is checked and it still plays stereo even tho on Itunes it shows a Channels: stereo, dolby digital 5.1. Same as the movies I have that are encoded by handbrake which say the same thing.

It works now.
