Mostly repeated from the old thread...

I've been ripping some DVDs with Handbrake for play on my N900, using these new DSP drivers. Even non-720p h264 m4v videos play much more smoothly. Unfortunately there does seem to be a correlation between the N900 clock speed, the kB/s rate of the video, and gstreamer's willingness to begin playing the video.

freemangordon stated this is likely a mafw-related issue, since lowerlevel gst cli can launch just fine. For my part, I intend to investigate this by ripping the same sample at multiple bitrates and testing playback.
