I seem to recall something about the LZX compiler doing some kind of
obfuscation on the byte code.
Maybe that's why the length of the arguments after an opcode is wrong?

Hi! I'm glad to help, and look forward to Gnash supporting Flash video!
I've checked the video stuff into the OpenLaszlo subversion tree at the
lps/components/extensions/av -- low level video components
lps/components/av -- high level video user interface components
demos/youtube -- youtube demo
demos/videolibrary -- video library demo (requires Flash Media Server
test/video -- various video tests
If you want to run the YouTube player in debug mode, to see if there are
any warning messages in the debug window (and to see the mediastream
status callbacks), then you can open it with this url:
