* If your video files' format is supported by your device but have a high video bitrate, then your device may not be able to decode and play them in real time. This will be a limitation of the device's firmware. As an example, some devices can stutter when trying to play Blu-ray rips that have video bitrates of 10Mb/sec or higher. In this case, trying lowering the video bitrate when encoding/ripping your videos. As a test, you can try to pre-transcode the video to another format and see if that plays. | * If your video files' format is supported by your device but have a high video bitrate, then your device may not be able to decode and play them in real time.
