I have a Axim X5.I download audio content (Radio Shows)from the internet to a sd card or cf card. The MP3's in question are 10 to 12 Mb's and the shows are 30 to 35 minutes long. When I pause the show around the 17 to 18 minute mark into the show is where I have issues. When I want to start playing the track again the Windows Media player says its playing but no sound comes out nor does the program advance. After 10 minutes of no sound the show continues right where I paused it. Any Clues ??
