Scenario: I built a 25 second .swf movie that will be played on a laptop, used as a time filler during church service on a large projection screen. F.Y.I. The .swf will not be used to stream on the web at all. Problem: plroblem is, on the laptop the .swf file plays slow and jerky. The audio ends before the movied does. However, on my system the file plays correctly. I notices that the movie speed varies from one system to another. Question: Is there a way to make my movies play at the correct speed and smoothly on any system it is played on? Maybe some of you can ask me the right questions to give me the right awnsers I need. Thanks! SWF File Statistics: 30 fps 640 frames 10 layers total file size 924 Kbytes uncompressed
