@Phako : I copied the config options from BraviaEX.conf to N900.conf for PS3MediaServer for codec compatibility. Now, I dont see any exclamation marks when I browse Ps3Mediaserver . But, I am still unable to play any file as still get the following INFO 2012-05-08 23:08:20.694 [StartPlaying Event] renderer: 192.168.72.108, file: /home/user/file.avi INFO 2012-05-08 23:08:24.701 [StopPlaying Event] renderer: 192.168.72.108, file: /home/user/file.avi While this happened, PS3Mediaserver actually showed that it was transcoding the file , but soon stopped it due to the playback stop event shown above.
