Hello, I'm working at a film festival where we receive a lot of mp4/H264 files with 5.1 sound. The files will be screened in cinemas with Dolby Digital Cinema Sound Processors, but also in other locations with only stereo systems. Also the playback system will be different in each location, some will have PCs, some Laptops. We are verifying every file before the festival so it doesn't have any drop frames, stuttering or audio errors. The problem is : can I verify on my home system (laptop with no sound card, VLC player, stereo system ) the video files with 5.1 and then play them in the locations without something going wrong then? Or should i keep converting the 5.1 into Stereo, as we did last editions and everything worked fine.
