I am able to convert a DVD to my blackberry 8830 WE using Mobiola Video Studio. All works well until about 20 to 30 minutes into the video. Then the video becomes choppy and the audio goes out of sinc. I see that there is an option to "split" the file. I am guessing I need to split the file into smaller parts to avoid the choppiness of the video. Any rules of thumb on splitting the file. Or, is there another reason myvideos are choppy after about 30 minutes or so??

Thanks
