Dear Mike velte,
thank you for your tip. I tried to do what you told me and it seems to have worked out even if with lower quality… I compressed from premiere to mpeg2 and then tried to burn with nero but had the same problem… shortly before the burning proces was through, it stopped so I let nero just “burn” to the harddisc and then from there I put the ts_video file into sonic and what do you know… it worked. So if sonic is a problem to my other programs as you think, should I delete it?
