The current solution of the DVBViewer adressing the problem with your card, is not reliable enough, so i'll switch back to MediaPortal which does work perfectly. It sadens me, since DVBViewer is such a great product. I don't see how this can be fixed easily, without serious testing. And i don't think that i can help this process. But since there are only a few people who experience the problems, i understand that it simply has a very low priority. So i shouldnt obsess about it and just use the solution that does work.
Thank you anyways for your effords.
