Someone please help! Here's the situation. I have movie files that I download off the net that are SVCD MPEG2 files. I use a 3rd party program called "(S)VCD2DVDMPG" to make the files DVD compliant. After I do that, I author them with DVDit. I'm able to author the files with no pronblem. Then it comes time to burn the file onto DVD. DVDit starts processing the file, transcoding the audio, etc., then when it gets to the VERY LAST PART, right before it's about to burn the file onto the DVD, I get the following message:

---------------------------------------
Could not complete the last command because
the GOP structure in the cell starting at
00:00:00:00 in PGC "pres 3" could not be
broken into VOBU's
--------------------------------------

What is that? Can someone PLEASE tell me what I'm doing wrong to get that error message? ANY HELP would be GREATLY appreciated!
