Hi, I am new in this forum. I would like ask if anyone can help me with some code advice about using code for video with as2.

I am using AttachVideo() function for external flv videos and play them with play function play(urlvideo). My videos are some 3d animations rendered as avi with black background .

Can anyone help me about the following:

1. I would like to replace the black backgrounds on the external flv with some flash action scripted graphics as mc, while the flv video is running. Is there a way to use action script to simulate alpha channel for the black backgrounds (to make them transparent) on the rendered flv. ? Can you give me some code advice ?

2. Can I play/stop or pause external videos during their play?
(something similar to gotoAndPlay() function for the mc)
For example:

- I would like to avoid the first part my video and make it to start from its 100 frame or just to stop on the 100 frame on its duration.
- Can I play my external video from end to begin (similar to Backwards Effect)
I would appreciate you answers with some code advices or samples.

Thanks of lot.
