Hallo!
This is embarrassing for me. I didn't test very well before posting that email: When i play it on my computer there indeed is sound (while plying it on the standalone dvd-player i have in reach there wasn't). I apologize very much!
no problem !
Even better would have been some kind of subtitle to know who says/thinks what...
I was thinking that too, but later realized that it might be a social "contract" with those who participate in the video, i.e. they might not (all) want to link their real person with their virtual person.
I don't think that this would be a problem ... ;)
LG Georg
