Can anyone help me with the following problem:

I've convereted the 3 Star Wars teaser trailers into .mpg files using TMPGEnc. These files have been converted ok but when I try to make a SVCD using VCDEasy after I've selected all the options and clicked burn I can only get a certain way through before I'm asked to insert an empty disc. I also get this problem if I specify to write to my C drive (which has 18 GB of space left). Any help on this would be greatly appreciated.
