Please keep in mind that you can try to watch these
online (if you have a broadband connection) to test.
Also you can try to save the last two, to see the
actual download speed.
Note: The last stream is 1.5+Mbps,
so you will need a minimum of a 2Mbps dedicated high-speed
fibre connection to view it online (it will saturate
a T1, DSL or cable modem). Most users should probably
save the last file instead of viewing it.
