As you know, there are three ATP indoor events and one WTA event in Europe this week. If you'd like to watch live feed of the ATP events go to http://channelsurfing.net/ and scroll down the page. TLM is airing Grand Prix de Tennis de Lyon, Eurosport is airing Davidoff Swiss Indooors, and an unknown channel is showing the St. Petersburg Open. Sometimes only a marquee matchup is shown so depending upon what time you tune in, there may not be any tennis.
There's no link for coverage in Linz, but there is the ITF event in Bratislava is being shown on Infonet.
