I have come to the conclusion that Tmpgenc standard vcd output is not entirely standard compliant, although on initial inspection it would seem to be.

I have a terapin and a napa both of which have difficulty with tmpgenc vcd standard files although this is much more pronounced with the napa.

I have used panasonic, wintv pvr, lsx , cce tmpgenc, bbmpg, and even nero to make a variety of test clips, and the only one that consistently gave problems on the napa was the tmpgenc clip.

The napa plays terapin, panasonic, wintv pvr, vcds flawlessly, I have used mpeg repair to analyze the differences and have come up with nothing. I have kept std. GOP, bitrates, res., etc and yet the only way to get the napa to play tmpgenc output is with the napa bitrate modification template.

Anyone have any thought?
