NERO Burning disc doesn't match edit version

[NevadaTom]

I'm using Windows 7 on a Intel i7 machine with 12GB memory. I'm having all kinds of problems with the Blu Ray or any other HD video I make (even recording directly to the hard drive).

The version I see on the edit screen is exactly the way I want it but the burned version is VERY problematical. At first there was a 2-3 minute segment in the middle of the video that was pixellated and jerky. Playing the original from the camcorder directly into my TV set was fine.

I finally concluded there was some stray bit in that clip that was confusing NERO so I cut out a few seconds right were the problem starts and that fixed THAT problem.

HOWEVER, now the last few minutes of the video goes completely black although the audio is fine. NERO reports that the burn was successful in every case. No error codes at all.

Ideas anybody?
