Clueless in Seattle

Here's a screen shot of what I see on my monitor:I'm sure I've made some obvious blunder somewhere along the way. Maybe this will give you the clue you need to point it out to me.

Thanks LIGHTNING UK! for that lightning fast reply. I checked my settings and I did indeed have Output set to Device. But the Media tab is still missing under Advanced.

I'm running ImgBurn 2.5.7 on an old P4 PC running XP Pro I'm trying to follow the instructions in the guide How to create a double layer DVD Video image file using ImgBurn I got as far as the 7th screen shot where is says: "Next go to Advanced -> Media and ensure you have selected the appropriate profiles for the media you're intending to write to." In the guide's screen shot it shows a row of four tabs: Dates, Media, Restrictions, Bootable Disk But on my screen all I have are three tabs: Dates, Restrictions, Bootable Disk The "Media" tab referred to in the guide is missing. It's just not there. What do I need to do?
