My BDP9600/12 can almost not play any Bluray (and some DVD) and not stutter after approx 5 minutes and then gets worse and worse and even stop playing back the movie, very annoying.

I have tried connecting the BDP9600 to my tv without going through any receiver or anything else, even tried different HDMI-cables but no change.

For example the Blueray "Men In Black 3" (5 051162296171) behave like the above...

Is there anything I can do? or do I need to send it in for service?
