Here is what I sent to TSN:

I have just been through the French Open tennis coverage and the coverage starts at 10ET in the morning. I cross-checked this with the coverage of ESPN/2 and their coverage starts at exactly the same time BUT they have coverage beginning from 5ET for 5 hours on ESPN Classic. I don't know if this has been overlooked but normally you get the feed from ESPN and the coverage is near enough the same, hopefully there is some way for you to get the coverage from ESPN Classic as tennis fans would be missing 5 hours of coverage a day because of ESPN moving their coverage to ESPN Classic. It is the same problem for Wimbledon as well but it is only 3 hours missing.

Can people who like to watch tennis please relay the same message (in your own words ) and hopefully this can get changed, I am hoping this is just an oversight on there part.
