Anyone good with Veritas NetBackup?

Hello, I am new with Veritas NetBackup and we don't have support contract. This responsibility was dumped on me. My only question is this: We have 240 media slot(robot) and a media list of over 3000 from previous backup etc. What i want is a better way to run a report that will show me which tapes in the robot are full or near compacity, ie =>200 gig and such. right now what i'm doing is, I print out the list of media from my robot and then compared it to the report from media list, which shows me all status of full/active/froze state and also gives me the size of occupy data. I can't figure out a way to get this info to show up on this view when i check the robot. Does anyone have any idea what i'm trying to do? sorry if its not too clear. I can't find a way to change the layout or view on the media robot that will show me these important info. thanks, S
