ICAL link confuses users

We should come up with better mouseover title (explanation) for both the iCal (feed) icon and the Calendar (download) icon. Current text:

Calendar => Download iCalendar entry for this event.
iCAL => iCalendar feed for this event.

For the 'download' icon, perhaps this would be better:
'Add this event to your Calendar'

For the 'iCal Feed' icon:
'Subscribe to this event from a calendar that supports iCal feeds'

• original post —
  The iCalendar feed button/link on event registration thank-you page is confusing my users. I understand that the URL is intended to be copied into another application, but I've had several users tell me "I click the ICAL button and all I get is a page of code."

Not sure what the best approach is to remedy this...
