I believe you are both experiencing a resource conflict (perhaps the overlay).

The only solutions I know of are the following:

1 - Try setting ObjectDock to no magnification and z-order = alway on bottom.

2 - If you want to have magnification and the z-order at normal, or always on top - then your alternative would be to unload ObjectDock while watching DVD's.

Any DVD viewing is very demanding on both the front side bus, and the processor.

The introduction of dual core processors is an attempt to prevent these issues on future computers.

The only real fix is to turn off Object Dock while you watch a DVD.

The only media player I have found, which works properly in full screen mode with OD turned on, is VLC media player. It is free and can be found here: Link

In that kind of setup I think your limited to dragging the "Entries" into the order you want. I'm not aware of a method that would allow you to "sort" dock items.

I'd probably suggest resorting the customer directory and dragging onto a new dock while deleting the old one each time you add customers. Sounds like a major pain.

My method is to create a single entry to the directory and have it either display as a menu or bring up the directory window. It's not the same but you can sort the same way you do anywhere else (right click).

Try BlazeDVD, it supports all audio which in my books, is a good thing. Supports all output formats. The support is sitting on basic for me but the good thing is, it has live chat. It has an ok skin, nothing too gross to look at. Supports XP, 2000, 98 and ME. Also, the product isn't too pricy which is another good thing.
