How to load .png or tga-raw images as movie

In the sequence editor, I need to load a movie avi with alpha channel. The quicktime "animation/ millions of colors+ " codec works, but I’ve read that .png or targa raw can be used. But when I try it only lets me load one frame.
How can I load them as an avi ?

Goto Add >> Images, navigate to them and select .001 to .050 or whatever with RMB and hit enter then place your strip. If .001 to .050 are the only thing in the folder you can just hit A to select all.

Thanks.
Heh, after all these noob questions I’ve been asking, I should add to the wiki :rolleyes:
