Supported MNG File Editor?

I'm looking for an MNG editor/creator. I've tried one calledPNG/MNG Construction Set, but it does not create valid MNG files for the iHD spec. Anyone know of a program that will create valid MNG files? Thanks in advance.

Personally I have never created one, but a list of applications is at http://www.libpng.org/pub/mng/mngaped.html

The tool must produce a fairly basic VLC MNG; try using as few options as possible when saving the file.

In case nothing else is working you could do something like this:

<cue select="id('ani')" begin="0s" dur="1s">
<animate style:backgroundFrame="1;2;3;4;5;6;7;8;9" />
</cue>

<div id="ani" style:width="50px" style:height="50px" style:x="100px" style:y="100px" style:position="absolute" style:backgroundImage="url('1.png') url('2.png') url('3.png') url('4.png') url('5.png') url('6.png') url('7.png') url('8.png') url('9.png')" />

I have done that, from script though. It works and is virtually the same as what an MNG would achieve. Menus look much better when they are in motion as you are navigating around them.

what did you put in the script to call the ani?

I have some ideas but none have worked
