I love the surfing program on Rush HD. The PQ is outstanding. If you focus away from the surfer and onto am idle part of the wave you can see the reflections and motions as if you were right on shore.I love this channel.
If you like surfing, pick up "Step Into Liquid", it was produced by the guy who did Endless Summer and the PQ is outstanding. It also includes a HD WM9 disc if your PC has enough balls to run it (2.7 GB or higher processor).
