Once a downloaded video fails to play, streaming playback will be performed when the downloaded video is played back thereafter.

Question

When I perform the following procedure, the streaming playback is performed even though it has already been downloaded.
When I turn kill the task and launch the application again to play, it plays the downloaded file.
How can I make the download playback work without turning kill the task?

1. download the Dash video to the SD card
2. unmount the SD card from the device settings
3. play the video DLed in step 1
4. end playback
5. mount the SD card from the device settings
6. play the video DLed in step 1 <- Streaming playback is performed at this time
