I 've just noticed a new bug in windows versions (both: 64 and 32 bits: I've tried) I know you are actively working on the next version so I hope it will help to make it even better on every platform.

When you want to edit preferences and change default directory for DCP: the software always forget it. It always remains "My DOcuments".

I tried on ubuntu and the preference settings works perfectly on Linux. It fails only on windows.

An Idea BOUT SOUNDS for Still Picture DCPs:

Finally, I thought to a last thing when I was testing the software to make a still picture DCP with sound.
Adding sound to this kind of DCP is a great idea and the fact that you can add any sound in any samplerate is really useful but in most common cases, the simpliest way for users to add a sound for still picture DCP should be using a simple STEREO wav file.
So, it could be very useful to have an option to add a simple stereo wav file, just beside the existing "L,R,C,LFE,SRL,SRR" possible entries.
I imagine this simple stereo sound would be managed by DVD O MATIC as "L" and "R" entries.
Don't you think so? It could be an idea for the next release.
