My s300 (with v2.1 firmware) suddenly froze during playing the Happy Feet yesterday. I turned it off by pressing and holding the power button. When I trun it on again, the play show a "NO DISC" message on the front panel display as well as on the TV despite of the BluRay disc is still in it. I then tried everything to bring it back including reseting it. However, nothing worked. This morning I thought give it another go, but still no luck. Then a miracle happened - I put a DVD in it and turn it off then turn it back. so the player started with the DVD in it. Then it starts playing.. I tried the Happy feet again, it also played. so has anyone have the same experience?
