<p>Attempt to seek out of the buffered range. If supported, this
should cause a waiting and seeking event to be fired for each seek.
This test makes assumptions on the size of the input file, the bitrate
of delivery, and the duration of the file.
</p>
<p>
Source is assumed to be about 188k with a uniform bitrate, &gt; 4
seconds in length, and served at 25kb/s. This should make seeking one
second ahead every 200ms always leave the buffered region.
