Hi Jack

Yes it's possible. You're obviously converting to dvd format (or rather the 
software is doing this for you) which involves recoding the files according 
to the quality that's been chosen. A full dvd quality encode is done 
something like 8000 KB per sec. Lower qualities being done at lower rates 
(6000, 4000, 2000, etc) depending upon the quality you want. Which software 
are you using to burn it? There might be an option to lower the video rate 
for the encoding resulting in something fitting the dvd. On top of that I'd 
suggest burning at the slowest speed your burner supports to get the best 
burn
