'jitter' frustration on DVD

[hondo2160]

Hi all,
I am using DVD-Lab to author my DVD-R's (some cheap, some higher quality) and using TMPEG DVD Author's Writing Utility to burn them. The files are around 6000 kbps and the audio is ac3. On certain players I get a vertical 'jitter' of one or two lines every second. A little 'pop' where the picture jumps the tiniest bit.
On some standalones this doesn't happen at all. On my Playstation 2, the movies pause whenever there is a fade between scenes or white titles on a black background.
I have been all over the map, changing out media, software, players, and am still getting the same result.
Is this a bitrate issue?

Difficult to say without seeing it happen.

The usual cause for jitter is reversing the field order during encoding. It is easy to fix or check for - take the same video, use ReStream to change the field order, then make a new disc and test. If the jitter is gone, that was your problem. It does seem odd that it doesn't happen on all players, but perhaps it just isn't as obvious. It certainly isn't a bit rate issue, as I have used much lower bitrates without having anything like this happen.

As for the PS2 - very little would surprise me about it. The PS2 is a poor DVD player. Older versions are even worse. The first generation used a software DVD player instead of hardware, so it wasn't very reliable at all.

The first questions I would ask are

1. Does this happen on commercial discs ?
2. Are these fades in the video stream, or at the end/start of titles - i.e. a title break ?

Well, I re-encoded my files using the DVD-Lab quick encode and all is good.
Seems like it was a bitrate issue.

If you want to drive a playstation 2 nutt's , shove "pitch black" in it ... the first 3 minute's really give's it a work out .
