aha, yeah this was brought up over at myspleen. This is not the SL version I created. Although this one is probably a bit better quality than the SL version I made. I originally released this DVD as a dual layer disc (was nearly 8GB). I then made a single layer version using DVD-Rebuilder and CCE with a 5 pass encode. I do not recall, but the extra stuff may have still fit on. This version you downloaded was created by a friend using the same method, only with 10 passes, so it is probably a bit better video quality that the SL version I made.

I included all of the original .swf flash files in the DVD_ROM folder. I would recommend omitting these when you burn the DVD. you get all of this footage on the DVD video anyway (that was the point of this DVD). I just included them originally in the DVD_ROM folder on the dual layer version because I had some room left and the files are relatively small. Removing those should clear up a bit of space for you. You can keep these on your hard drive or just get rid of them. I would recommend NOT re-encoding the DVD to be able to include this material on the DVD. It would degrade the video yet again.

I hope this answers your question. Let me know if you have any more. :)
