So I have finally fixed the choppy video issue on the Hero and, as others have reported, it's a direct result of the encoding bitrate - if you limit your bitrate to 584Kbps (audio + video) with a wired headset - no stuttering! If you limit slightly further ~460Kbps (audio + video) you will get no stuttering even during Bluetooth streaming!!!! Yahoo... here's the problem.... Using the Act1 Video Player front end, I get a 1/10th of a second delay in the audio over BT (isn't present with wired headset)... does anyone else have this issue and/or a solution? I have tried reducing the encode bitrate even further and the result is the same... Any advice welcome!
