New Release - Firmware Version 1.06.04 for WD TV Live Streaming Media Player (1/10/12)

you’re saying that you put a file on the root of a usb connected drive (to the live streamer), and can’t get rid of the file now?  have you tried connecting the drive directly to your pc and making sure that the file has been properly deleted? 

[edit]

It seems possible that the file may have been corrupted when you moved it.
