It seems that most video files I try to play on my AndroidTV have an audio/subtitle delay of about 750ms. I've tried different players (like VLC, Archos...), I've tried running the file from USB, from SMB server (through X-plore, since I could never manage to open a shared folder straight from a video player app), tried different file formats, and there's ALWAYS this delay, no matter what. (Always? Sometimes I don't notice this, but maybe the delay is there.) The delay is not present when I run the video from my PC. Also, I don't get delays when I watch videos on Netflix, for example.

Any ideas? I know I could use, say, VLC, to adjust the delays, but it's really annoying to do this for every single file I open. Any idea of what might be causing this? Is there a fix or a more definitive work-around?

TIA
