can you try removing it from the player via your computer and see if other files play OK.
Okay- I played a video file (all video files have been virus-scanned, so rule it out as a possibility) and it basically froze ten seconds into the video. An hour before this happened, all the sound stopped working. I turned it off, I removed the battery and put it back in, I even deleted the file in question, but nothing is happening. I don't know why, but it's stuck on this one frame of the video file, and none of the buttons work. Any suggestions?
