I have a question. If I have a FBC tuner, can I record a tvshow while Im watching another tvshow/movie?

you could do that with a twin tuner - its basically 2 tuners that are independent of each other

An FBC tuner is like 8 conventional tuners, so you could record 7 shows while watching an eighth

a twin tuner would require a twin LNB and 2 sat cables, one to each tuner.

An FBC tuner would require a unicable LNB and will run down just one cable.

People always ask how many channels can I record. If you ask, how many transponders can I record, that gets rid a lot of the misunderstanding, although there will need to have more details later.

Single tuner (not FBC) plus universal + Single signal supply = You can view/record one transponder. You will comfortably record/view 12 channels without a problem. Excluding encryption issues

Multiple tuner (not FBC) plus universal LNB + Single signal supply = You can view/record any one transponder + one more on same plain(quadrant). Universal LNB is locked into high/low, vertical/horizontal plain

Multiple tuner (not FBC) + multiple universal LNB = You can view/record any two transponders if you have two tuners. The LNB ports are independent are each will do what it needs.

As an example, if you have a single Terrestrial tuner. You are locked to one transponder/multiplex. You are not limited to one channel. You can record all the channels on that transponder/multiplex. For the UK, as an example, most people will be able to simultaneously watch/record BBC 1 HD, BBC2 HD, ITV 1 HD, Channel 4 HD,

FBC tuners do not need unicable and will work with universal LNBs. You wont get full benefit. I have got to 30 channels using a universal LNB.

An FBC tuner is 8 tuners. 2 have signal wires connection points , other 6 do not.

If you use a Unicable LNB/switch, you can record as many transponders as you have tuners configured. It is not 8 channels, it is 8 transponders

FBC Tuners + single universal LNB

You can record from any one transponder. The other 7 tuners will work in loop through mode. So you can record as any channels as are on all those transponders

FBC Tuners + twin universal LNB

You can record from any two transponders The other 6 tuners will work in loop through mode. So you can record as any channels as are on all those transponders

If you get a Unicable LNB/switch, then answer will be yes.

There is no "one FBC" tuner, it s a group of "8 tuners". So by one FBC tuner, if you mean one FBC module, then lets go with that. I presume the channels you want to record are all one satellite.

FBC tuner use multirecording only if you have SCR or Dcss lnb dont forget it.

He is using a Cable FBC tuner.

I have a dreambox 900 (2020) dvb-c FBC tuner.

Also I use dream elite right now. I cant do my registration process so its impossible to write to them in their dream board support.

only recognise 1 tuner. I can lok att 1-12 channel (com hem basic) when recording.

But not the other channels.im getting a dark channel. How can I Solve this problem?

I have no experience with dream elite (or any dreambox for that matter)

Can you load openATV to your dm900 and try there ?

At least you know you can count on support from the ATV team.

You can record two channels separately on the same transponder with any single tuner. Unless there is a plugin for it, there is no way to merge/playback two recordings as one.

On live view, you watch both channels simultaneously using Picture in Picture. A single tuner device capable of PIP will do this

I presume you have two tuner cards, not four cards. So you have a total of 16 tuners. But only 4 connection points.

A universal LNB can only be in one plane/polarity at a time. For example, if it get the voltage to be in high polarity, it cannot receive channels in low polarity. A unicable LNB or switch does not have this restriction. If you are using a universal LNB, the 6 tuners on each card will only work in internal loop through mode.

There is no simple answer to your question because it depends on what transponders you are accessing. And how many wires you have to the receiver from the LNB. I have got to 30 channels with one card (i.e 8 tuners) using a universal LNB.

It's not channels, its transponders. For each tuner with independent signal, it can independently access a transponder. Even a DM800 with one tuner can record/stream as many channels as they are on transponder.

You should get a unicable LNB and splitter if you want to get the most of your receiver/tuners.

You have edited your post while I was responding to your initial post. My answer now does not fit, please ignore parts of my last post that do not apply, as you have unicable.

Draw a picture of your wiring please.

Which LNB are you using? ( I want to establish how many SCR it has.)

Are all 16 tuner set correctly? Correct = match the reception hardware each tuner can access.

Picture of wiring please, it avoids all the questions. and prevents misunderstanding.

What is tuner configuration of each tuner?

Is there only 1 channel on each Transponder on 30w?
