strange burning and playback

My latest project was a short (4 minutes) family video, which I put out in DVD format so I could share it with friends and distant family.

When I burn the final edited project to the computer's HD it plays well there, smoothly and without interruption, except for a 25 second period which is replaced by a solid green screen. I've repeated the burn a few times, always with the same results. It looks as if 3 or 4 of the very short clips have been replaced by solid green. On the computer's HD, play will continue without any prompting from me, after that 25 seconds.

When I burn the same video to a DVD disc, play sometimes halts after about 30 seconds, hangs up for several seconds, and then resumes. Play may be hesitant, jerky, and intermittent for a while after that. But once again the solid green screen replaces a few clips of video. Playback will hang up at that point, and the video will not play further. I've tried re-burning the video to four different DVD discs, always with the same results.

Other short video projects burned to DVD have not had these problems.
Discs are Sony DVDs.

Clips are fairly heavily edited, with changes in backlighting, brightness, saturation, modest increase in sharpness, and very heavy noise reduction. (Intrusive visible video noise remains even after heavy noise reduction - but that's not the problem I'm asking about here).

Check with the video card manufacturer for the latest driver.

Green screen often comes from a old video driver.

Don't bother with Windows Update, MS never has the latest driver.

Thanks Carl - I'll check out the video driver. After I wrote to the forum here, I re-did the whole video with no edits at all, and it played normally. Maybe I over-edited it so much that the driver couldn't handle it.

abslayer - The video was produced in DVD HQ format before burning, but remember that I had made extensive editing changes to it. Maybe I was waaaaay over-enthusiastic about the editing. I think my expectations of what can be achieved with the DVD format are unrealistic.

That could be a ram problem I see no reason if you have enough memory that PD could not handle what you did.
