Nerovision Express 3 (OEM) - one title only?

I was using Nerovision Express (2) as part the Nero OEM package. I downloaded the updates, and I’m now running Nerovision Express 3.

When I build a DVD by importing two AVI files (and they are large files - >2GB each), only the first one can be played from the menu.

The menu shows both titles, and you can select the second title on a DVD player, however it simply does not play.

You can get to the the second title, by pressing the “next” button on the DVD player whilst the first title is playing, just not from the menu.

Does anyone have any suggestions as to what I am doing wrong? (BTW this is the OEM version). Comments welcomed!!!

Thanks P.
