Hi, I can make a push left transition using the following XML:

<TransitionsAndEffects Version="1.0" >
<Transitions>
<TransitionDLL guid="{D1C5A1E7-CC47-4E32-BDD2-4B3C5FC50AF5}">
<Transition name="Push Left" iconid="33" >
<Param name="Bands" value="1" />
<Param name="SlideStyle" value="Push" />
</Transition>
</TransitionDLL>
</Transitions>
</TransitionsAndEffects>

after following the instructions here:
http://msdn.microsoft.com/library/de...iemakersfx.asp

Does anyone know how to make a push right transition?

Many thanks,
Tony.

YAY!! I've finally had success.
Here are the steps I took, which will hopefully help out any other
newbies like myself.
1) Went here: http://www.rehanfx.org/pipplus.htm and installed PIP Plus
15 day trial ($8 to buy).
2) made a file called "push.xml" at this location: C:\Program
Files\Movie Maker\shared\AddOnTFX
3) copied and pasted the following into push.xml:
<TransitionsAndEffects Version="1.0" SpecialIconFileID="1033"
SpecialIconResourceID="101">
<Transitions>
<TransitionDLL guid="{D1C5A1E7-CC47-4E32-BDD2-4B3C5FC50AF5}">
<Transition name="Push Left" iconid="33" >
<Param name="Bands" value="1" />
<Param name="SlideStyle" value="Push" />
</Transition>
</TransitionDLL>
<TransitionDLL guid="{4EF98DF5-794F-4fd3-8E77-559F82C8D10C}">
<Transition name="Push Right" iconid="0">
<Param name="RectA" value="0.0, 0.0, 0.0, 1.0, 1.0; 1.0,
1.0,0.0,1.0,1.0" />
<Param name="RectB" value="0.0, -1.0, 0.0, 1.0, 1.0; 1.0,
0.0,0.0,1.0,1.0" />
</Transition>
</TransitionDLL>
</Transitions>
</TransitionsAndEffects>

Done! Use Push Left and Push right.
