Custom components

Hey there people of earth,

I’m trying to create custom buttons to use with a flv file. essentially i want to use the Media Display component and create my own controllers to control playing the flv. So I found this doc via macromedia however I get hung up on step 11 as it doesn’t seem to work.

Does anyone have any good links on explaining how I can create custom buttons to control a flv?

OR

if there is a good book that will help me learn more on creating custom components for Flash MX Pro, would be greatly appreciated.

Thanks in advance,
Mark
