I am using the Divx Converter set to the Mobile option...I converted a video and it starts to play, it unfortunately then starts to get really choppy and then stops. I am using an HTC Touch Pro 2 from US Cellular running WM 6.5. I can play similar videos done in MP4 format with higher bitrates, basically a conversion for TV presented IPOD and they work just fine. Any help would be appreciated. Thanks.
