---3) I connected my device to my "mpeg4 digital tellestrial television decoder with USB input
XORO XRT 7600" in order to record a video file.
4) Initially the decoder start recording on the MP4 device (the record lamp was visible).
5) After some recording time the USB was suddenly and without reason disconnected. The XORO decoder was not
able to detect it as a USB Flash drive anymore----
If your player did not work after doing this, I wonder if you may have damaged the input and also the firmware device from overvoltage??
