Tennis Channel HDAlthough they were shooting for August, the Tennis Channel launched in HD on DirecTV last Wednesday -- along with CSTV. These latest additions bring the total to 59, which while impressive, is far from the 100 that was promised at CES last year -- no wonder they don't seem to have press event scheduled this year. The Tennis channel started producing HD content earlier this year and moving forward, all documentaries, series, and specials will be presented in our favorite format. As expected, most of the tennis tournaments will be in HD, including all US events, and many international events like French Open.
