Thanks LArry, ggrussell. I probably wasn't clear in my previous post...
The DVD burned using my laptop with MyDVD 5.2, a NEC ND-5100A burner and NVIDIA GeForce FX Go5200 Video Adaptor works fine.
The DVD burned using Media Creater 9 MyDVD, my old GeForce 2MX, and NEC ND--3550A had the problem with skips whenever the screen is mostly black.
So... I put in a newer video card - a GeForce 6200 (256 Mb) - on my desktop but with that and the Media Creater 9 MyDVD and NEC ND--3550A it still has the same issue.
So - my question if anyone knows the answer is - how does MyDVD 5.2 encode DVD images differently from Media Creator 9 MyDVD ?
The DVD Media I am using in all tests (those that work and those that don't work on my standalone players) is TDK +R single sided.
As always thanks for the help....
