Here is a screen cap of an imported video properties.
Yes I do get mattes... My PC monitor is 4:3 so I expect to get mattes on the top and bottom when playing 16:9 videos. However when I play the completed DVD on a DVD player (not on the pc) there are mattes top, bottom, left and right.
I might add at this point that I use an IFO editor to make the DVD's loop, and have been using Nero to burn the final copy. This could be the problem (Nero). I am going to do some more experimentation, and will get back to you with my results.
Thank you for your time...
p.s I put in a suggestion that you may want to incorporate an IFO editor into your suite of Apps.
