I wanted to give my feedback, on the modification hereunder based on 9.3 which is already out (impressive work!).
- Setting to turn off logo Arcadeflow from the screensaver is working. That is Great for all CRT users
- Autoupdate is working like a charm... that is awesome !
- I tested the attached layout.nut, that improved a little bit, but then try the videosnaps from progettosnaps on original layout.nut and it was even better. So let's forget emumovies HD videosnaps.
I now do understand that for Mame roms set which all have their proper resolutions, this is not a perfect solution.
Base on your explanation you do take a number of row up and down which ever the rom (game) resolution is and zooming to fill in the screen ?
That's why some rom (game) are more recognizable than others based on the frontend resolution.
Why not take into account the information stated in the resolution.ini for example here attached (This is from category.ini also from progettosnaps).
It would allow you to find out the proper resolution for each rom/game.
Would that allow you to adapt the screensaver resolution of Arcadeflow ?
Thanks again
Cool, I got my mame videos from here: http://www.progettosnaps.net/videosnaps/ and they are at the correct pixel resolution with correct display aspect ratio, but since you have pixel perfect snaps I can fix the layout to make it work with your videos 
That sounds like music to my ears, thanks a lot !
If you want to beta-test the feature, you can try with this attached layout: just put it inside your Arcadeflow folder. But before doing that make a copy of the current layout.nut just in case.
This version should use the static snap resolution to set the video resolution so you should be able to see a bit more of your video 
If you want to see even more, look for the line:
scanrows = 180.0
and increase it, be careful though that if a game has less than the lines you put there, it will look pretty bad.
