Arte HD is a DVB-S2 transponder using the 8PSK modulation. Locking goes without any problems at all. > On Astra HD+ and Anixe HD im getting an error : > Astra HD+ en Anixe HD is on a DVB-S2 transponder which is using a QPSK modulation. > -- SNIP -- > > If you need further informations let me know. > I tested other DVB-S2 transponders which have a QPSK modulation. All these didn't want to lock and gave a timeout. DVB-S2 Transponders with a 8PSK modulation did gave a lock (Hotbird has a couple, while I don't have subscriptions to chose channels, I'm able to lock those). So my first impression was, it's a missing parameter in the Frontend struct. So I made some changes and check if the transponder is DVB-S2 and added parameters for DTV_PILOT (with data PILOT_AUTO) and when QPSK is used with DVB-S2, to use the NBC_QPSK modulation (which is needed for DVB-S2 if I'm not mistaken) instead of regular QPSK. However, didn't bring me the sollution I hoped for. I now have a timeout, lost lock and regain lock, etc, etc, etc. But it's more then it was before. So I'm close. Currently I do have a small problem where I put in parameters which shouldn't been given (oops!) and now my DVB-card doesn't lock any more, I need to reboot first. I hope to start to work on it this further when I'm done with work. I'll keep you all posted :) BTW, I did manage to get DVB-T working. At least it locks on on the encrypted channels, but I didn't had time to check for image. Mainly since DVB-T is my backup for channel-viewing and I wanted to focus on the DVB-S2 problem. > cu > > Edgar (gimli) Hucek > Regards, Niels Wagenaar _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
