MP4 files with 5.1 AC3 Audio. Will our old DVD theaters recgonize the 5.1?

[Zeeshan Ali]

I used to download MP4 files, a lot of them. I was not doing for quilte a long time.

I always found great video quality in mp4 and play them from USB port of 3d supportin TV.
Some time when I played 3D videos I always missed the 5.1 surrounds. I remember until 2018 I was able to find no way other than to play a 5.1 DVD .

Now recently I notice many mp4 files are mentioned with (5.1)!

Will they work If I play them on my theatre USB. I do have port! however I wonder if old DVD thaters by Samsung purchased 8-9 years from now, will be able to recognize the 5.1 AC3 sound?

Anyone have any such experience?

Try playing some mp4 files with 5.1-channel AC3 audio and find out for yourself. If the files don't play with 5.1 sound then you'll have your answer. Performing this little experiment can't damage your equipment.

You can do experiment as advised by usually_quiet or check is there Dolby Digital logo on your equipment... If Dolby logo is present then on 99.99% cases everything should work correct.

A model number of the Samsung DVD theater would be useful to determine what it is capable of playing.

For myself I use a USB port in my BD player.( It is an LG manufactured in 2012 & has no Cinavia detection)
The Display function of the BD player shows the Audio being played.
Further so does my Denon receiver that the Audio is played through.
