BlackBerry

I have a BlackBerry 8330 Curve and recently purchased the Motorola S9 Bluetooth Stereo Headphones. The device was paired and connected and I have no trouble listening to my music files, answering calls, placing calls or any other controls. The only problem I've had is the fact that I can't get the audio on video files to play via the Bluetooth Headphones. I have tried this on other 8330 Curves and experienced the same problem. However, on other BlackBerrys' (the storm etc.) the audio on video files play great. A work around or any information on how to correct this would be greatly appreciated. FYI, I have also tried the same with a different make Bluetooth Headphone and get the same scenario.
