I've actually discovered, that the mobile version does indeed have the time you watched added the watched event as its actually shown when syncing. However, if you then export the xml, you'll see that the time in the timestamp is 00:00:00 which it shouldn't be.

Thought I'd added a piccy and the xml :-



the xml is :-

  <Events>
    <Event>
      <EventType>Watched</EventType>
      <Timestamp>2007-09-22</Timestamp>
      <User FirstName="John" LastName="Smith"/>
    </Event>
  </Events>

Where as an event entered on dvdprofiler using the 'Watched By..' menu option you get :-

  <Events>
    <Event>
      <EventType>Watched</EventType>
      <Timestamp>2007-09-12T16:01:16.108Z</Timestamp>
      <User FirstName="John" LastName="Smith"/>
    </Event>
  </Events>
