CorePlayer Video Freezing

[sonicboom]

I have Coreplayer 1.2.1 installed on my Sprint Touch. When i watch a movie from my microsd card the video will freeze on a frame for about 15 seconds after 3-4 minutes of smooth playback. The audio continues to play seamlessly while the Video freezes. I assume the video freezing is due to the video buffering, but i have played with all of the buffering options without any fix. Has anyone else had this problem and/or does anyone know of a fix so that the video just plays right on through? Thanks!
