Isn't the problem here simply that the Atom N270 CPU in these netbooks
is insufficiently powerful to decode a 1280x720 h264 video stream in
realtime?  There isn't any GPU video decoding acceleration available at
this point, and decoding that clip takes a full core of my
(substantially more powerful) Core 2 processor.

You can take video display entirely out of the equation by trying the
pipeline:

“gst-launch filesrc location=/path/to/file ! decodebin ! fakesink
sync=true”

If that can't keep up, then it's just your CPU being too slow; netbook
processors generally need GPU video decoding offloading to play decent-
sized videos at an acceptable speed, and h264 is a processor-intensive
video codec.
