Help!
I am using EncoreDVD, and on motion menus I am seeing a strange glitch. When the menu loops back to the start point, the onscreen image (from the DVDR) drops down about 2mm, and then rises back again before playing.
How can I correct this please?

Unless Encore is doing something weird (like storing a still version of the menu along with the animated one, and displaying it for a moment), I'd say that's being done by your player, and is not actually on the DVD. Have you tried other players?

Either way, try encoding the motion menu so that its last frame is an I-picture.

I'm going to assume I can do this in TMPGEnc Plus? There is no way to do it if I let Encore Handle the render for the motion menu.
As another idea, would adding a still to the end of the AVI do the same job?

I doubt it, the picture type has to be set in the encoder. In TMPGEnc go to the "GOP structure" tab, then enable "Force picture type setting" and then click on "setting" to define the picture types.

Did this, and it has helped a little.
Roll on version 1.5 of Encore, failing that it's serious debt & Scenarist time!!

Most players will freeze the last field while "rewinding" the menu. This means the image might appear to move down by one pixel. It shouldn't be 2 mm, though, unless your video monitor is 1 metre tall.

If this is what's happening, changing to a different authoring program won't have any effect. If you end the motion menu with a frame where both fields are similar, the problem will be less noticeable. Applying a 0.3 to 0.5 pixel vertical gaussian blur to the clip should do the trick.
