Ian,

Thank you for your reply.
I understand what you said, but I believe there is something else.
More then mirror, it ́s possible to have different images in Ipod Touch Screen and TV out. Like Youtube, when the controls is in Ipod and the Video on TV Out.
With VM PLAYER is possible to choose the video out with a virtual button in the Ipod screen, default Controls in Ipod and video in TV out. And MuMoni App shows different images in the Ipod and Video out, too.
I want to do something like this.
Thanks,
Jorge

Yes, I also want to use apple TV. I want all the possibilities COMPOSITE, VGA, HDMI and Apple TV.
Any device that the user of my App could have.
What is possible?
How to choose the Screen? (The own Ipod/Ipad display or external...)
Just play a video is good enought.
Thanks,
Jorge

Thanks for the answer,

About speed control , means the speed of the image movement, The time from the beginning to the end, when the image (small picture jpeg) cross the screen.
But I believe I can do this changing the time value above. (time = "2" or time = "5", etc..).
In others words, the image has only one ypos, and the xpos is increasing from the beginning to the end of the screen.
And the xpos change n1 pixels to the right and waits t1 m seconds to change again. Changing t1 I can change the time and speed. The image cross the screen about 2 seconds and start again. It seams the image has a continuous movement.
