Hi Shui di
This not be the best way to do it but it works

(using windows XP)
1. Right click on the video, select 'save target as' to your desk top
2.When it's downloaded on your desk top, double click it and it should open up.
However on mine it just sent me to a download page where it says to 'right click here and save as'
Do this and the video itself will be saved to your desk top.
Sorry if this is a long winded way, others might suggest better, but it does work, and you'll have plenty of time for tea while it downloads :lol:
