I think the reason why I don't see the aspect ratio icons depends on the various templates that I have created over time following lepa's post, and the various fields created in some way influence the new template.
I discovered, for example, that in order to display these icons, I have to modify the code by inserting (pretty) as indicated in the lepa template.If([Aspect Ratio (pretty),0],[v_LDELIM_ICON]<img src="tooltip:Video//AspectRatio//[Aspect Ratio (pretty)]" RemoveRight([v_LHEIGHT_TECH_ICON],3)Math(Number([v_LHEIGHT_TECH_ICON]) + 2)" valign="middle">,)/
As for the critic ratings, I understood that they were already available and, not seeing them, I thought it was my problem
