If loading the movies is taking a long time, then your best bet is probably to make the web request asynchronously, so you’re not blocking the UI during the request.

and how it would have this function

   
 jsonAsString = CreateObject("roUrlTransfer")
    jsonAsString.SetURL(URL()+"/movie.php?cat="+HttpEncode(category))
    json = ParseJson(jsonAsString.GetToString())
    return json.Videos

To make the API requests asynchronously, you’ll basically need to use ifUrlTransfer.AsyncGetToString(), then listen for roUrlEvents in your event loop. Once you get the result back, you can then set the contents for the grid screen row(s).

Alternatively, you could opt to work with SceneGraph instead, and utilize the Task node for retrieving your content.
