Ghost Whisperer, 7.30pm, Seven Whenever a network starts banging out first- run episodes in doubles, you can be pretty sure they’re not that pleased with the program or its performance. Delia’s First Ghost kicks off tonight’s two- hour marathon, in which ghost whisperer Melissa Gordon ( Jennifer Love Hewitt) ‘‘ comes out’’ about her supernatural abilities to her mate Delia ( The Practice ’ s Camryn Manheim), whose dead husband appears to be trying to screw her chances with dates. The disclosure doesn’t go well. This is episode No 41, and the one to follow, The Cradle Will Rock , is No 38, in which regular character Delia won’t have a clue. So much for continuity. American Chopper, 7.30pm, Discovery Golf metaphors abound in this episode, about creating three identical bikes to honour American golf legend Byron Nelson. Will there be three holes in one, or a triple bogey? Paul Sr, Paul Jr and Mikey have their work cut out, and tensions between them mount. Nelson retired at 34 and then refocused on charity work, which the American Chopper lads aren’t strangers to themselves. Guru Greg, 8.35pm, ABC This documentary follows former Australian cricket star Greg Chappell’s tumultuous term as coach of the Indian team. Narrated by John Doyle, it begins on that mystical day in May 2005 when Chappell took on the toughest job in world cricket: to coach India to World Cup glory in just two years. Was Chappell ready for the cultural phenomenon that is Indian cricket? Did he take on more than he could chew?
