Anyone here used the MYTV Advance decoder before? I heard it comes with PVR function. Anyone tried using it to record tv programs? Does it come with a built-in hard disk or need external drive? Anyone who have used this or are using this, please share your experience here. Thanks.

I am using the K2 DVB-t2 decoder to record digital tv to USB pen drive. Everything was working fine previously. However, recently, when I removed the pen drive and inserted it again into the decoder, the decoder showed "USB is inserted" at first. However when I tried to record or watch the recorded content, I got "USB is removed" error message. When I went into Settings, somehow the USB device was not detected. I tried with another pen drive and got the same results. Any idea what is the problem?

Really? I have just been using the box for less than a month.
