I created a dvd with pinnacle studio 9 and wanted to view the dvd by outting it in the dvd725h . The dvdrecorder did not recognize the dvd, but now won't eject the dvd. Pushing th eject button or switching off/on the dvd results in the automatic switch off of the dvdr 725h. Remarkable is that 2 seconds before switching off the dvd lights up red as if the dvd is being recorded.
