Solved Wanting to change the encoding of the video & audio file in DVDA.

I wanted to fit a large video project on a 25GB Blu-Ray disk, however after encoding to MPEG2 the render was 40GB. I went ahead and created a DVDA project then I realised I could not burn this to a 25GB disk. I re-encoded to SONY AVC/MVC 16Mbps and the file is now 21GB. When I deleted the original DVDA video file and replaced it with the re-encoded file I see all my links are broken. Can you advise a method to re-link them? The links appear to connect with the various items on the DVDA project but remain broken.

You may be able to re-link your existing menu structure, depending on what type of links they are.
You need to press on each thumbnail link inside the actual Main Menu screens and then go the Action controls in top right corner.
From the Drop Down lists, you can re-link to each video.



For compressing MPEG2 video for Blu-ray disc production, I use this excellent online Bit Rate Calculator.

Thanks for your reply Derek, but I had tried that route and the things like chapter thumbnail titles didn't appear in the 'Action' list. No mather I will start again and create a new DVDA project for the re-encoded video. I have never used a bit rate calculator before but I will take your advise and get to study up on it. Thanks so much for your quick reply, cheers.
