Crewnet is a hideous piece of web development if ever there was one. iOS can't handle the menus either.
I stumbled across this gem of a website recently which works wonderfully with my Geneva roster. You just upload the PDF file and it will convert it to a number of different formats which you can then import into your preferred calendar app. I export to .ICS format and import it into the iCal app on my Mac.
Geneva & Merlot Roster Import
It's free for the first two roster imports and then there's some sort of a fee, but given its usefulness, I'm happy enough to pay.
