Unable to render file larger than 4 Gigs in Sony Vegas 10 I have wasted over 8 hours trying to figure out what is wrong my program. I am trying to render a 30 minute file in high quality HD using the Main Concept codec, but as soon as it reaches 100% I get this error saying there was unknown error while creating the media file. Is this some sort of limitation to the codex or program? Is there a workaround?

Thanks.
Not sure what went wrong but I was able to render it in .wmv format. Must have been something wrong with the file itself.
