I've used and continue to use ULead video studio but I've never used a trial version. I thought the trial versions were fully functional.

One - I would go to ulead.com and register (free) and then go to the forum dedicated to Video Studio - there are tons of smart, friendly and very experienced users of the application that will help you.

Two - I would attempt to render your project as a video file and select mpeg2 720X480 which is normal base file for standard def DVD.

If VS 11 completes that then you should be able to burn to dvd using any dvd creation program.

Personally while I am a huge fan of Video Studio as a great program for most all consumer and even pro-sumer projects I don't care for its' dvd creation capabilities - like options for chapter menus - so I always use VS to edit, add effects and transitions and music or narration or whatever and then render project to common dvd file type so I can create a better dvd program (my personal opinion only) using Sonic's DVDitPE.

I'm not a fan of Pinnacle consumer editing programs but, again, personal prejudice.

The VS forum is pretty awesome and you can get answers in minutes and you can also search Frequently Asked Questions - good information.
