Fruits lend themselves better to sorbet.
But if you really want to do fruit ice cream, I'd recommend against using the custard/Philly method, which is already softer. Use a recipe that's only cream, milk, sugar. You'll want to remove as much liquid from the fruit first, and then combine the sugar with the fruit to make a syrup, since the sugar will trap remaining moisture.
Check the Cuisinart website, their recipes seem to just work.
