SOHW-1633S Problem

Few days ago I have bought this DVD recorder, no problem till now.
My pc was running a p2p program, I was watching tv. Pc was working alone.
unexpectedly DVD recorder drive led become orange and some seconds after the pc go to crash, the only one solution that I could make was to turn off the computer, but at the next start the recorder is dead, dead for 1h.
Now it seems to work, for safety i have overwrited the firmware.
Very strange.
Sorry for my english.
