DvbDream Community

First of all I would like to congratulate the devolepers for such a great piece of software. I have tried several similar programs and this one beats them all.
Secondly I would like to ask a question. I seem to be unable to scan certain transponders on the satellite. I've got a motorised system and when I point to Astra 2, I am unable to receive anything from transponder 10773 for instance. Other transponders seem OK, but there are some where I don't get any signal.
I haven't been able to find out a pattern, whether is high or low transponder or vertical or horizontal. It seems completely random.
The LNB seems to work fine with other programs as I seem to get the whole spectrum. Any suggestion about what to check.
Thanks for reading me and any ideas will be welcomed.

are u under coverage SEE HIRE
i thing this is a S2 transponder and your card don't suport fec 9/10

Thanks for your help.
Yes, that shouldn't be the problem. I can receive that transponder with no problems with any other program or even with my Kaon decoder.
It really is a pity because DVB Dream seems a much better program than others, but somehow, certain transponders seem to be ignored.
I'll keep on investigating. This has to be my mistake in the configuration, but I can't find the error.
