so, rendering the premire file into a video and burning to dvd as video is causing the system to hand. ( I think that's what you posted )
from checking with other software that does exactly the same thing, this is not an un-expected occurance, as the rendering of each and every frame is processor intensive.
the system specs you posted are an average bare bones minimum for video rendering.
theere are 2 things that MAY improve system performance:
1) make sure you have at least 200 gb hard drive space free for this process
2) add more ram. ( 4 gigs, 8 gigs, 12 gigs... )
max the systems ram out with the fastest you can.
