api call SetWatchedTimes failing for dvd rip

The SetWatchedTimes call is not setting the watched time for a dvd. It is working for a recording.
Below is extracted from a test using sagex
public static void main(String args[]) throws Exception
{
int mediaID = 7130249; // I feel pretty

testSetAiringTime(mediaID, 300);
mediaID = 7354220; // Chesapeake Shores
testSetAiringTime(mediaID, 300);
}

public static void testSetAiringTime(int mediaID, int secondsWatched)
{
Object mediafile = MediaFileAPI.GetMediaFileForID(mediaID);
Object airing = MediaFileAPI.GetMediaFileAiring(mediafile);
AiringAPI.ClearWatched(airing);

AiringAPI.SetWatchedTimes(airing, AiringAPI.GetAiringStartTime(airing) + secondsWatched * 1000, 1534948850L * 1000L);

System.out.println("media Title = "+ MediaFileAPI.GetMediaTitle(airing) + " IsDVD: " +
MediaFileAPI.IsDVD(airing));

long watchedDuration = AiringAPI.GetWatchedDuration(airing);
long watchedEndTime = AiringAPI.GetWatchedEndTime(airing);
long realWatchedStartTime = AiringAPI.GetRealWatchedStartTime(airing);
long startTime = AiringAPI.GetAiringStartTime(airing);

long sageSecondsWatched = watchedDuration / 1000L;

System.out.println("watchedDuration: " + watchedDuration);
System.out.println("watchedEndTime: " + watchedEndTime);
System.out.println("realWatchedStartTime: " + realWatchedStartTime);
System.out.println("startTime: " + startTime);
System.out.println("sageSecondsWatched: " + sageSecondsWatched);

if (Math.abs(sageSecondsWatched - secondsWatched) <= 3)
{
System.out.println("Sage shows watched time set to the desired time.");
}
else
{
System.out.println("Sage does not show watched time was set to the desired time!");
}
}
