Creating a video project file

[tan how khiang]

Hi, I've a problem creating video project file. Under heading Share, I create a file under DVD and follow up with DVD Video (16.9 Dolly Digital 5.1).
Next I receive a message about optimal project settings profile. There 2 options 1. to accept and 2 to cancel it.
UNder option 1 - when I key in cancel, the project created when played on my computer, the video segments did not run in subsequent and even stopped and ended abruptly.
Under option 2 - When I key in accept, the project created when played on my computer, shows some video segments have a small protion at the top and bottom cut off for a while and it restores back
to the full screen.

I do not know how this problem arises. BUt when I burned it on the DVD and played on the DVD player, both video project file created run smmothly.
Can someone help me to identify what has gone wrong?

Thanks
