Here's the thing: I downloaded a movie (AVI.) and used AVI2DVD converter. The size of this is 699 MBs, so I wanted to shrink it to burn on a DVD. I ended up with a vob file, but when I try to open the file in Shrink, I get a message that it is an invalid data file. Also the analyze and backup buttons are greyed out in the program. I clicked on that button to choose the drive and had 2 choices, both of which I got errors such as "No disc in drive" or "Invalid DVD, no matter which one I chose. I am using Imation brand and it is a DVD+RW. Since I am a newbie, I probably have no idea what I am doing. I have burned many movies onto these disks but all were in AVI format and which they come out really well. What I am trying to do is possibly make a DVD to play on our home DVD player, if that's possible.
