Fiddler is a web debugger that shows all traffic between your PC and the Internet. Fiddler does not itself have any special inspector for AMF content; it can only be viewed in the HexView Inspector, which shows raw bytes.
If you've installed a custom AMF viewer from a 3rd party, you'll want to send feedback to whomever wrote it so they can improve it to accommodate your content.
thanks!
