Some Chapter Frame Entries Exceed There Total Frames?

Ulead DVD Movie Factory 2, when on the last stage of Converting Videos prior to Video/Audio Multiplexing a home movie to DVD including a few Chapters, the process halts and a promp appears as per the subjet.
Can any one help please, I have tried a defrag on the drive, re-rendering the video and changing the chapters, some times this helps and even if I shorten the overall video by 5 mins it can solve the problem but it takes so long to make a DVD then to get a prompt like that prior to finnishing It become depressing.
The original vids are annalogue captured and converted to Mpeg2, edited in Ulead Video Studio 7 and played to ensure Video and Audio match before converting to DVD in Movie Factory 2
Thank You regards Tony
