Cheers for that.
Essentially, what you suggest is how I'd envisaged doing this in the first place. But someone on these pages had suggested the method I ended up using [of course, now I want to quote it, the search function doesn't seem able to find it...]. Given the limited software I have and my unwillingness to purchase any more, it seemed a relatively simple way of doing it.
Before I scrap the hours of work done so far and start again properly, can anyone tell me how to recombine my audio and video files???
In case it came out a bit jumbled above, what I've done is use DVD Decryptor to rip the DVD into separate audio and video files. I've then modified the audio files so that the soundboard recording is mixed in. What I need to know now is how to burn these files back to a DVD - I'm guessing it has something to do with the .nfo file, perhaps?
If it does come down to using another (proper) program, have I got any freeware options available to me?
Thanks again,
Yousef
