Ok so when I schedule a recording, the first 15-20secs might have 1-3 picture frames but has audio in background.
I tried the .ts file from server to laptop playing on VLC and media player and there is no lagging of frames
So I linked the vero4k to the .ts directory to play through video and not associated with TV section. and it does the same, also tried a file with a higher bitrate in same folder and this played fine.
So at least i know networks fine, but what else could cause this?
