The other day I had just finished my video project and wanted to burn it onto a DVD with a menu and everything, so I went through the whole process and left my computer running...about 6 hours later (when I got back from a friends party) I check up on it assuming the DVD is done burning....low and behold i see this:

So naturally, since this is a particularly big file...I decide to give it some more time and leave my computer on overnight....I wake up about 10 hours later, and I see the EXACT same screen, except the elapsed time has risen to about 16 hours...Whats going on? is there something in my video that is making it take this long? Is it supposed to take this long?
