Once the DSP is wedged you have to reboot (if it hasn't spontaneously rebooted already). I can confirm Nokia 770 GStreamer implementation problems. It is used in MPlayer (in not a very clean way, but that's another story) in order to get mp3 audio decoded by DSP and reduce load on ARM core. I also observed system instability supposedly caused by starting/stopping audio playback: http://maemo.org/pipermail/maemo-developers/2006-August/005232.html Also most likely GStreamer is responsible for MPlayer lockups when trying to play relatively long flv files as observed here: http://www.internettablettalk.com/forums/showpost.php?p=22855postcount=207 I know that IT2006 just switched to a new version of GStremer, and bugs can be expected.
