I have to eat a bit of crow here

, I tried DvdFlick on the demonstation file
sample fileand it worked fine, thinking that the LLV vol 16 files would be the same I recommended it's use. I have now downloaded vol16 and I get the same audio error as DP.
I'm not giving up just yet I have left a bug report on the dvdflick forum and have split 4 meg off the intro file to test. Sorry for the erroneous report but I will let you know if I get a response.
To Chris - have the file formats changed between the sample and the latest LLJ?
Also the mp4 seem to be at 18 FPS is that a standard setting?
