First of all i just want to thank all the developers for doing a great job!

I have however a problem that is a big showstopper for me.

I cannot change channels between 2 different satellites (2 different diseqc ports) I get a cannot start graf error og no signal error. After that error i have no problem starting the channel but just changing channels between eg. diseqc A/A and A/B on the same card is NOT possible.

I have 2 dvb-s cards in my system, and if both of them are enabled i will not get the error it will change to the 2nd card after hanging for 10 seconds but this is not an acceptable solution for me. i have attached 3 different log files.

1. both dvb-s cards enabled
2 only the technotrend card enabled
3. only the hauppauge enabled

I believe that it is a bug and not a driver/hardware issue as it happens with both cards.

Hopefully a dev can look into the issue and fix it :)

Maybe other users can confirm?

Well, as long as i stay on the same diseqc port i can tune the channels fine first time. Its only if the channel im changing to is on a different satellite that the problem occours. Also my problem is not only on HD channels

You are correct. It seems to be the same issue. I just did not pay attention to the other thread. I think the subject on that post is misleading.

Hopefully the devs are looking into it.

    Looks like diseq command are not send; or freq. not changed correctly.
