Audio/Video Issue

Hey folks,

I'm new here in this forum so first I wanna say HI to everyone. Wishing you all a great day.

I hope I'm in the right section for my problem since I worked with resolve but I don't really know if there lies the problem:

I've finished my project in Resolve (using the 17.08 Beta) as always. So far I had no issues.
Watching my video on PC - everything is fine. Watching upload on Youtube - no problem so far.

Then I watched the Youtube video on my TV. And the audio/video sync was about half a second off. Same on my Android Phone. First I thought about issues with the Youtube Upload. But I also uploaded it to my Google Drive and there's the same problem. Watching it on PC works totally fine. Watching it on my phone and sync is off. Same when I download the file. Render settings are the same with all other videos I did so far and had no issues.

Any ideas why there's a difference between the devices and if there's something to do about?

thx, Thomas

I'm thinking this is a problem with the TV, or the method you use to play it back there.
