was it tennistv.com that you could buy old finals matches from using your credit card?
I just remember that they were offering a sample of the Nadal-Kiefer 2008 Toronto Final
If not what site was it?
I just checked, and you can see old tourneys online but there seems to be no way to record them.
For recent tournaments, you can subscribe either by tournament, by men's/women's matches, or by year.
