Versus used to be called OLN. It's on channel 151, no HD on Dish, and I believe you need, at least, the Gold package to get it.
From wikipedia:
Versus' programming is an unusual mix of extreme sports, more sedate fare like hunting, and, most notably, coverage of professional cycling and ice hockey. Versus currently owns the American rights to live coverage of the Tour de France. Versus also acquired the cable rights for National Hockey League games as The NHL on Versus. It also picked up the U.S. rights to the new A1 Grand Prix series, and the National Lacrosse League in a Saturday primetime "Game of the Week" format for the 2007 season. It also airs weekly Arena Football League games.
