It appears the reason this works is because that file has a 1/1
pixel-aspect-ratio for the video. It fails with files with non-1/1 par, because
the playsink videoconverter bin is using the 'identity' path instead of the
videoconvert ! videoscale path for some reason. An additional observation:
everything works fine with the deinterlace flag removed (e.g. just
flags=video).

To reproduce:

gst-launch-1.0 playbin
uri=http://people.freedesktop.org/~tpm/samples/bbcnews2.m2t
video-sink=ximagesink
