My friend got recently received a dm900 and he has a question. I'll handle his problem, maybe you can help, or it should be like that you can't use it like he wants.
So his story is here:
I connected both tuners to the dish. 1st tuner with diseqc ABCD the second with a rotating dish.
When I start a recording on NPO1 HD tuner A is occupied but never the less it should be possible to continue zapping with tuner B. This seems to work. However, when I choose a channel on the same transponder where NPO1 HD is being recorded, the message is shown ‘no signal’. This can only be solved by rebooting the box.
I suspect that there either is something wrong with the firmware or with one of the tuner(s). Did you ever experienced an issue like this?
I will test with a completely different image, probably like you proposed, Newenigma.
So, if he takes a random other twin tuner like a Zgemma box, he can make a recording and whatch all other channels via the second tuner.
("Via the tuner that is occupied by the recording I should be able (and actually can) whatch all channels of the transponder of that recorded channel. When I use a card and not a CI.")
We want to know if this behavior is normal and the box uses a common resource (that's what I think), or is it a some kind of software bug.
I'm gratefule if someone says something smart. I think the configuration, what my friend uses is not very common, that's why I decided to ask for help here.
