Video with audio playback

I want to playback a video with an audio track, but when I use FileStream and connect it to VideoTexture and AudioOut I can xor playback video or audio.
couldn’t find anything in the forums about it.

as a workaround you could use 2 filestreams: 1 with Video, 1 with Audio.

but i also wonder why that shouldn’t be possible?!?!?
