How to insert DTS soundtrack?

Hi

I have 2 DVDs of “The Shadow”

One is DTS (full bitrate I think) and pan/scan

The other is DD 5.1 and Widescreen

Can anyone please advise the best way for me to create a DVD with the Widescreen image and DTS soundtrack.

Ideally I would want to burn it to a DVD+RL DL to maintain the original’s integrity.

I am happy to remove all subtititles and DD5.1 soundtracks.

Software I currently have is CloneDVD / AnyDVD and I have downloaded IFOEDIT (which I find very confusing!)

Also is there a good manual online for IFOEDIT?

I am a newby.

Thanks

Bob.
