Tony, The problem you are having with the width and height is because the SWFis compressed. The "CWS" signature tells you that the swf is compressed (Gzip), "FWS" is an uncompressed SWF. All the bytes after the 4th byte are compressed. i.e. "CWS" "versionbyte" then all are compressed. the signature and SWF version (1st 4 bytes of the file) are not compressed. swfdump -d filenamein.swf -o filenameout.swf will decompress the file.
