Player/Image Object "always buffer" Problems

[Dave]

Hi Scott,

This is weird, it doesn't work here. What happens if you set  
"alwaysBuffer" to true?

I don't understand a couple of things about your snippet:

>    set the currentTime of player 1 to (F * the timeScale of player 1)

In my case the timeScale is 600, so frame number * timeScale would  
give values that are way off. I multiple by 24 which is (timeScale /  
FramesPerSecond = 24). In this case FPS is 25 (I'm hardwiring this at  
the moment since I can't find out how to get this info from the player).

>    set text of img _display to myVar

is there a difference between this and:

  put myImageData into image "ImageThumbnail"

It would be nice to know what "alwaysBuffer" actually does. It could  
be that there is an old copy of the buffer being used, or RunRev  
doesn't think the image has changed.

Thanks a lot,
All the Best
Dave
