Black Screen, no play



using Remake 3.5.3 I followed the steps to merge two DVD5 dvds.

I did the following:

  1. I added Two VIDEO_TS folders using “Import DVD” function.

  2. I used Tools>Merge to merge the DVDs. I got a new project window named as Project 3.

  3. I used “Export DVD” feature to get the DVD files in a HDD folder.

The problem is the when I play the files all I get is a black screen. No navigation is available. What am I doing wrong?
