Hi,

I installed a new scr unicable lnb, it works fine with the dvb-s2 and dvb-t tuners of my tripletuner dm800se japhar sim.
My question is: is it possible to modify the dvb-c tuner (hardware or driver) to obtain a second free available dvb-s2 tuner for the streaming?

This is not possible, as the Tripletuner in fact is a Single Tuner, to which you just can change the mode to C, T or S2. But only 1 at a time can be used.

To have a Dual tuner, you need to use the normal Tuner board (or this TestTuner named TripleTuner), and put for example a DVB-T or DVB-S2 tuner on a USB Port. Then you will have a real 2 Tuners.

There is also the original Dual Tuner S2 available, with Japhar Drivers for the DM800HDse. Perhaps this is the best option for you (Si2166B Dual Tuner DVB-S2, if you want C/T2 you have the Hybrid Dual Tuner - Dual Tuner, DVB-C/T2).

I don't know how works the "Scr Unicable", some are capable of receiving few streams from different frquencies with 1 tuner only, but this is in fact the LNB capable of doing so, not the Tuner.

Hi Jan,

Thank you for reply, So for triple tuner 1 tuner only available in modality s2/t/c.
I searched for USB dvb-s2 tuner but not found.

PS

Scr unicable enables one coaxial cable from the antenna equipment to multiple tuners, to provide independent tuning across the whole range of satellite reception for each tuner. So if the box have 2 s2 tuners it's possible to see one channel on TV and second to stream, or watch ones and record second (not depending of polarization)

Exactly, check this one below, this is your solution, but naturally you need LNB to support it,

ok, but I want 2xdvb-s2 + 1xdvb-t2 😁
cause my scr lnb have dvb-t2 input also

You can install the Dual DVB-S2 tuner above, and add a USB Tuner that is DVB-T (or DVB-T2). But remember that the DM800HDse is only capable of H264, and NOT H265/HEVC.

yes, I think it's better to buy a new generation 4k box.
Thanks for support

I would actually go on a real Triple Tuner DM900UHD or DM920UHD,

Is that you mean?

If yes, so the tuner will be uhd capable (dvb-s2x) and the dm800se not, is that right? This tuner is also multistream capable so multistream will work on dm800se or not?

Hello,

This tuner is Dual yes (Dual DVB-S2), as Toysoft indicates, and compatible with DM800HDse as well as the DM900UHD/DM920UHD. It's not Multistream.

Admin

Can you tell me please which USB Dvb-s2 tuner will be compatible with the dm800se?

The one you quoted,

Admin

P.S.: This tuner is NOT Multistream, so NOT DVB-S2X... It's DVB-S2 Dual Tuner compatible with DM800HDse (Japhar Drivers support it) as well as DM900UHD/DM920UHD.

Hi, quoted tuners are plug and play, you wrote in the second post about a USB dvb-s2. can you tell me which one is supported?

I ask this cause the plug and play tuners are more expensive than a new cheap 4k box..

ps
the one sold by hm-sat in the description said dvb-2sx multistream

HM-Sat wrongly describes it as multistream,

USB DVB-S2, there was one tuner, supporting Dreambox few years ago, Sundtek DVB-S2.

Searching on internet I find,

- Hauppauge WinTV-Solo HD
- Hauppauge WIN TV Nova-S2
- Sundtek DVB-S2 (this one was common and had it's own auto-install drivers).
