We have a page with the address of
http://russia.tv/video/show/brand_id/(some_digits)/video_id/αβγδεζ,
where 'αβγδεζ' is the number at the address end (6 digits).
You can download the clip posted in the page from
http://cdn1.vesti.ru/_cdn_auth/secure/v/vh/mp4/low/αβγ/δεζ.mp4?auth=vh&vid=αβγδεζ (poor quality), or from
http://cdn1.vesti.ru/_cdn_auth/secure/v/vh/mp4/medium/αβγ/δεζ.mp4?auth=vh&vid=αβγδεζ, or from
http://cdn1.vesti.ru/_cdn_auth/secure/v/vh/mp4/high/αβγ/δεζ.mp4?auth=vh&vid=αβγδεζ (superb quality).
Besides, you can get the thumbnail address from the 220th line of http://player.rutv.ru/index/iframe/video_id/αβγδεζ (look for 'http:\/\/cdn1.vesti.ru\/vh\/pictures\/b\/288\/###.jpg'; '###' is the three digit thumbnail name).
