Europe is not USA, so you'll have different channels and tv rights in different countries.
Eurosport has Australian, French and US Open here in Romania so I guess all Europe has them on Eurosport 1 and 2? Including the HD versions. Don't know if they buy for all countries, should be a hard fight
Wimbledon and all Masters 1000 + London Finals are on a local channel, probably a channel has 1000's and everybody negociates Wimbie sep.
