gstreamer windows7 nightmare

Hi

I had been using gstreamer on winxp, i migrate my project to a new windows machine. The new computer has a windows7 64 bits, i do the same steps as i do on the xp machine where the projects run ok.

In the new machine (win7) i can not play a video with alpha, so i can not use any video with proress or animation codec, i have another videos that use photo/jpeg and they are working ok. So i think that the problem is in the codec…

Has someone using gstreamer on a win7 machine on codeblocks ??

Thanks for reading!!
