ulead dvd audio sync error on long progs

[yoffieee]

I am trying to get a 45 min prog onto a dvdr using ulead dvd workshop.
I have my mpeg2 file on the desktop. It plays ok in sync all the way through using media player. When I create my menus in ulead the audio is still in sync. I then create a .iso file. This is then burned to a dvdr on pioneer a03. The disc plays ok but after 15 mins the lip sync starts to go. By the end its about a second or more out. Anybody know what the fix is??
Is it to do with I frames or something?

Check to see if you are using DVD workshop version 1.3, if not download the update from ulead and install it.

In the burning window there is an option that turns of the re-encoding of compatible mpeg files which should be checked.

Oops, sorry for the late reply, I missed this one.

Did you solve the problem? If not and you upgraded to version 1.3 then it should appear when you "Finish", the project and burn to disk. Note, it logically doesn't appear if you select "Burn From Disk Image".
