Two practice session videos are available for download:
Direct download links on dhool (low qual):
(1) aadhi manidhan - http://www.dhool.com/ms/msps1.wmv
(2) kaatru veLiyidai - http://www.dhool.com/ms/msps2.wmv
Rapidshare links for high qual clips:
(1) Kaatru veLiyidal kaNNammaa: http://rapidshare.de/files/4799428/Prac-kaatru.mpg.html
(2) aadhi manithan: http://rapidshare.de/files/4800840/Prac-aadhi.mpg.html
These files are on rapidshare servers. Once you click the link, it takes you to a page where it asks for "free" or "premium" account. choose "free". It asks you to wait for some seconds. Please wait. Once the waiting time is over, the link for download appears. Do a "save target as".
However there is a limitation that rapidhsare servers do not allow you to download more than 20 MB within an hour. My suggestion would be to to download the low quality clips first and high qual clips later.
