Hi,

I've produced a couple of DVD's in which the video becomes jerky (but the audio remains in sync!) either right from the start or after a certain point -DVD1 after 2hrs (its 2hrs 15mins long), or 20mins (its 1hr 7mins long).

I've used Ulead VS6, Tmpgenc, Ulead DVD MF2 and previously ahd great DVD's produced. Anyone got any ideas what could be causing this?

Oh, and I've defragged the discs recently and dumped a lot of redundant video files afterwards., so the discs should be in good shape as far as capacity is concerned.

Bill
