[Gnash] SWF8 is not fully supported?

[Steve Smith]

I am using gnash-0.82-3.fc8.x86_64, with the related plugin, to run swf files in firefox, on a x86_64 machine.  My operating system in fedora core 8. When I access sites such a YouTube and try to run video, I get the following message in my log file:

25132] 18:53:55: UNIMPLEMENTED: SWF8 is not fully supported, trying anyway but don't expect it to work

I then get the following error messages further down in my log file:

25132] 18:53:55: ERROR: On ActionNewMethod: no object found on stack on ActionMethod
25132] 18:53:55: ERROR: On ActionNewMethod: no object found on stack on ActionMethod

22013] 19:25:50: MALFORMED SWF: Bitmap fill specifies '65535' as associated bitmap character id, but that character is not found in the Characters Dictionary. It seems common to find such  malformed SWF, so we'll only warn once about this.

Has there been a fix to these problems?

Thanks
Steve
