What about music files. I put several songs, pictures, and a few videos on a micro sd card. The JPEG pics worked fine, the MP3 songs worked fine, but WMA's were not recognized, and out of the few videos it only recognized MPEG-4 videos. Then it started having problems recognizing the memory card and giving me errors when I clicked on the music, video, or picture icon. Reformatted the card and put the stuff back on it and same end result after going into stuff on card. I am running Android 1.7.4.
