This problem just started to occur 3 days ago. Every couple of disks which I insert into the drive (doesn’t matter what kind cd, dvd) it will just spit the tray back out after 3-5 seconds. The light never goes on and I simply reinsert and all is fine. Running BSMB firmware.
It happens to me too , but it is realy funny when I figured out why .
The disc have to be seated very well in the tray
sounds like optical pickup head gone bad to me or the optical pickup head need to be cleaned. Did you use the original DVD movie disc or burnt disc??? could be region setting problem too.
