Sorry I should have been more clear. At present I am experimenting to see if I could achieve what I would like to do. Using Sony DVD Architect, you can make great menu interfaces but it compresses the videos and I don't want that, so I thought I could change the videos back to the originals with Imgburn. I have'nt made a complete bluray compilation to find I have wasted my time so as an experiment I have put an intro video, then a menu with a button to replay the intro, hence why the file is so small. I did successfully change the video but the button on the menu didn't work on the rebuild. Just in case it was something to do with what I changed I rebuilt the original ISO I made, but this also stopped the button on the menu working.
The Original ISO is 697MB and the rebuild is 691MB. I use Elaborate Bytes Virtual Clone Drive to load my ISO's and play them with PowerDVD18.
I find it odd because I understood from a lot of different sources while researching this that this was the program to use and that it retained the menus. I can only assume I have perhaps not set the program up properly to achieve this, but can't see my error. Hopefully you will be able to assist me, thankyou
