Hi!
I spin for the first time last night with 5.0.3 and it was, how can i say that... it was a disaster...
So, when video was play, we can see some glitch ou some lag, first time I ever see that with rekordbox. Sometimes, when load a new track, sowftare freeze... but music continue to play. But the video stop few seconds.
I was thinking, maybe my macbook pro need to be restore because it was a long time.
So this morning, i restore to macOS High Sierra. Download rekordbox DJ, install XDJ-RX Driver. Restart.
I install my playlist backup, all was good, everything came back! But.
Start a video, it's take 4-5 seconds, same problems, laggy, freezing sometimes when loading a new video...
Everything was perfect before, and my next party is for the 31... I don't what that in front a big crowd...
Someone have this issue right now?
thanks!

@Martin > rekordbox video is quite demanding on the system resources, what is your computer's spec (CPU / RAM / etc)?

What is the video quality setting in the rekordbox preferences?
Middle!

And have you ensured that there are no other applications or tasks running in the background (eg. Spotlight indexing)?
Yes! I’m using this MacBook only for my DJ’s stuff!
Never running others software at the same time! I’m now thinking
About try with 5.0.2 to be sure!! ;)
Try with the beta instead?
No, but I can try if you want! :)
Test done, same thing with Beta 4
