When batch is in progress does or should the frame counter be sequential or should it flutter between 10 fame 8 frame 14 frame 9 frame.

I did a dvd burn and the first minute was good then i got big square pixelation

It wouldn't shock me if that was happening because MPEG2 has temporal compression. Only every fifteenth frame or so in an MPEG stream is "real" (the I frames). All the others (the P predictive and B bidirectional frames) are comparisons to each other. In order to do the comparison, the program has to jump around.

That could be a different problem. Symptoms like that can be caused by poor quality blank disks or very high encode rates. The blank stock check is easy. Buy a five-pack of Sony DVD-R disks and see if the problems don't go away.

If they don't, the problem may be datarate settings. The going theory is never encode over 7 in order not to overload the older DVD players. Some of the DVD Studio Pro High Quality settings go as high as 7.5.
