I've never had that experience. I've had files with 20 mins of silence. Their bit rate shown by the player was like 32 kbps or something, despite LW showed it as 320 or 190, etc. I see those types of files as another earlier form of fake files. When you do a search, check the bitrates carefully. If you see a file at 4 MB at 192 kbps & another at 4 MB but 320 or something then try downlding both & see which one works properly.
