I have problem with security settings in Flash 8. Macromedia implements new security to Flash 8 because they think that flash player may have security holes. It’s nice, but problem is with backward compatibility, and I think, that’s big problem.
So example.
You have application on web, which should play “many” long videos to its users. It would be problem download many MBs of videos, so you rathers store videos on user’s hard drive. (No matter how you will copy videos to user HD, e.g kiosks). But now it seems, that you cannot load any file from local disk, if your application is on web. It is possible in Flash 7, but not Flash 8.
I have tried allowDomain commands, set settings in Macromedia Global Privacy Settings Panel, try all I know to load video from HD, but I had no succes, it seems, that this is not possible in Flash 8?
Am I right? If yes, that’s problem, because imagine situation: You have application written in Flash 7, and have million users, and now they upgrade their flash player to 8, and they will see no videos 
I think, this is problem.
So, anyone, please tell me, if it is possible to handle such situations? Anyone from Macromedia tell us, if this is possible. We have our clients, which choose us, because we had convinced them, that Macromedia have wonderful tool called Flash, which can do such thingy. So now Macromedia convince us, that we were right!

1. Create ‘local.swf’
2. Create ‘network.swf’
3. In ‘local.swf’, place a button with this code:
loadMovieNum(”http://www.yourspace.com/network.swf”,2);
4. Upload ‘network.swf’ to the above URL
5. Run ‘local.swf’ IN THE FLASH 8 PLAYER NOT THE BROWSER
6. Click your button to load ‘network.swf’
7. When the security box pops up, click Settings, then Edit Locations>Add Locations>Browse for file
8. Find your ‘local.swf’ and select it
9. Shut the browser window that opened
10. Now, open your ‘local.swf’ EMBEDDED IN HTML IN A BROWSER - click your button again
11. ‘network.swf’ now loads
12. Make sure in your Flash Publish settings you have selected ‘Local Playback Security = Access Local Files only’ - (not sure if this makes a difference actually)

Have you heard anything definitive from Macromedia?
Either Flash 8 was designed to prohibit a browser-based swf from accessing local files or it wasn’t. This issue is pretty much black and white.
I was relying on this functionality as well so I too would very much like to hear THE ANSWER. Though I think I already know it: NO.
