Unwanted frame at the begining of edited video

[CadMonkey]

Lets say I start with a captured Mpeg2 video from my HTPC of a movie I want to put on DVD. Lets say this video stream starts with a memorable image of a 700 lb. woman laying on her bed (cause she's too fat to sit up).
Using MF4, I scroll through to the start of my movie and "mark" it... then similarly "mark" the end. Now I finish the menus, and what-not, and when its done it starts with one frame of the fat lady (the first frame of the original stream), and then goes into the movie. The rest is exactly the way I set it up. I re-tried several times and keep getting the same thing. I even tried splitting the video at the start of the movie and deleting the first clip.... same result. So, I tried starting over with a different movie, and I get the same thing... the first frame of the original gets left in.

I'm using the downloaded trial version of MF4. I've been using MF2 for a while, so I'm familiar with the process. MF4 seems to be set up pretty much the same.

Any ideas?
