The following website just launched last week: www.racefanstv.com
They are showing all the 2009 coverage of the BTCC, DTM, European LeMans and many more races in their entirety. They also have some 2010 Eureopean LeMans races and plenty of historical stuff.
I also found the 1962 Indy 500 video where AJ Foyt won his first of 4 Championships. The link is here - and this video is scheduled a few more times today along with the 1961 Indy 500: http://www.racefanstv.com/channels/o.../indycar/1543/
The easiest way to see what is scheduled is to click on the Program Schedule menu item at the top.
Wow! A real competitor to SpeedTV.
