Quicktime not rendering TexML for some?

I am trying to use quicktime in-world for rendering text.. (and there could be some video on the fly..)

I see the symptom where it works fine for several, and the screen is black for others. Not sure if this has to with media texture, quicktime version, lack of fonts, etc.

The TexML is below. If anyone has a lead as to why it will render for some, and not for others, I'd sure appreciate hearing about it! (yes, I am writing a quicktime RSS reader)

<?xml version='1.0'?>
        <text3GTrack trackWidth="1000.0" trackHeight="1000.0" backgroundColor="100%, 100%, 100%, 100%" language="eng">
        <sample duration="6000" keyframe="true">
        <description format='tx3g'
                horizontalJustification="left" verticalJustification="top"
                backgroundColor="100%, 90%, 80%, 100%" >
                <defaultTextBox x="0" y="0" width="980" height="768">
                </defaultTextBox>
                <fontTable>
                        <font id="1" name="Arial"></font>
                </fontTable>
                <sharedStyles>
                        <style id="normal">  {font-table: 1}
                                                        {font-size: 24}
                                                        {font-style:normal}
                                                        {font-weight: bold}
                                                        {text-decoration: normal}
                                {color: 100%, 50%, 0%, 100%}
                        </style>
                        <style id="link">  {font-table: 1}
                                                        {font-size: 24}
                                                        {font-style:normal}
                                                        {font-weight: bold}
                                                        {text-decoration: underline}
                                {color: 100%, 50%, 100%, 100%}

A friend of mine, Van, was tired of having so much crap in his home
office.  So he decided to mount all the extras (route, external
drives, modem, etc.) underneath his desk.  Now he just has his
laptop, monitors and keyboard/mouse on his desk.  The link provides
lots of great pictures and simple instructions.

My first guess would be that people are using different versions of Quicktime. Maybe the ones who cannot see the text are using an older version?

thanks Vlad.

May I have a couple of others try it? (see 1st post)

Could it be a font thing?

Anyone have .smil -> TexML that I can take a look at? An interesting experiment would be if I can have my lsl script point at something that's generating text.. I need to eliminate variables...

Hi, My first guess would be that Vlad Bjornson is on the right track, I have the same problem with some of the movies we produce, using certain codex that are not available/included with older versions of QuickTime can cause some not to see anything.

Having said that, I spoke to someone recently, that was using XP SP1, said he had never updated windows either!!!

For general information NET.Framework 3 is now available from microsoft's main website, it add more rendering enhancements to the API, useful for the SL Client, when used with DirectX 9.0c
