Hello all,

 

With the recent announcement that OpenPLI will stop support for Dreambox, I am considering replacing my DM8000 by a VU+ Duo². I used to use the Newnigma image and moved to OpenPLI this summer when Newnigma 4.0 came out. This image was twice the size of OpenPLI and had very infrequent updates as they were based on DMM which is a crappy image.

 

I was also never impressed by the quality of the DM8000 video. I used to have a Topfield receiver and I saw a big difference, especially with HD channels, when I replaced it with the DM (the Topfield was broken)

 

Questions:

 

1. How is the image (video) quality on the VU+ Duo? Better or worse than DM8000?

 

2. Can I re-use the soft CAM binaries from my DM on the VU+? I would suspect so as it is also a MIPS CPU

 

3. Has anyone else done such a move (from DM to VU+) and if so, what is your experience?

 

4. I see the VU+ Duo can only run the OpenPLI v4 image but I am running the v3 image on my DM. Is v4 as stable as v3?

 

5. I also see from the VU+ Web site that they have their own image with support for Dual Display. What is it based on? This Dual Display feature seems interesting is it possible with OpenPLI?

 

6. Any comments/suggestions?

 

Thank you

Hi,

 

1. I don't know.

 

2. Depends on which softcam you use. But yes both are MIPS based

 

3. No

 

4. Yes

 

5. Dual Display is just the front color LCD where you can display many informations. You can customize it from the plugin LCD4Linux which is pre-installed in OpenPli4 VU+ Duo²

Thank you Pr2,

 

I got confused. The feature I meant when I said dual display is actually the feature called "transcoding" which allows to stream to a Mobile device (Android, iPhone, iPad). Is this possible with OpenPLI?

[WanWizard]

The only box that can do that at the moment is the Duo2, and only limited. So the feature is there, but not mature yet.

That's the box I'm thinking of getting. By limited, do you mean it is limited by the hardware or by the image?

[WanWizard]

No, limited by a combination of drivers and image.

 

Currently the problem is that if you enable transcoding, the drivers claim the tuner, which can then no longer be used for all other purposes (transcoding requires full and complete tuner access).

But it doesn't tell Enigma that, so if a recording starts, it will start on the same tuner, recording either nothing, or the transcoded stream instead of the original stream.

Hi,

the Solo2 can also transcode. But every E2 Box can stream in your local network since years. Transcoding is mainly needed when you want to watch local TV over the Internet.

1. How is the image (video) quality on the VU+ Duo? Better or worse than DM8000?

The picture quality is by definitition equal on all receivers that are connected using DVI/HDMI.

[WanWizard]

To be complete: because it's a digital signal that is send to the TV as it is received, without alteration.

[pieterg]

Not always without alteration, there are several settings which affect the output such as scaler and deinterlacer.
If you use the wrong values for these settings (or the drivers have the wrong defaults), you can certainly mess up the picture quality.
If the drivers provide access to all these settings, things such as wrong defaults can be fixed.

But to answer your question, I'd expect the vu+duo2 to (roughly) have the same picture quality as the dm8000.

[dirocca]

i can confirm that the picture quality of the duo2 is exellent.

The vuplus duo2 has one advantage on this point (shared with the xp1000, et4000 and vuplus solo2), it can output at 1080p50/60, effectively making it bob&weave, the receiver may (or may not) do a better job at that then your television. If you connect a computer monitor that doesn't deinterlace, it's definitely better.

[icebreaker]

I would definitely wait for the Xtrend ET10000  

This will be the best receiver of all times.

[zzzzz]

No I wait for VU+ Quadruple 

perhaps on market year after next year.

After what I heard it can also boil eggs.

[Erik Slagter]

After what I heard it can also boil eggs.

My dm800 could do that years ago

[icebreaker]

the 4 tuners vu+ box that will be launched in 2-3 years will get extremely hot like the duo2 , so you can use them as heaters for your living room. I understand why you can boil eggs with them

6. Any comments/suggestions?

I have both boxes (Duo2 and DM8000) in use. In my personal, (very relative) comparative list Duo2 is in all points the winner

But don't forget: many Duo2 users have daily hardware and software problems with their tuners. I think that DM8000 has a better tuner/pip management.
The zap speed is on both boxes identical.


On DM8000 I used (till now) mostly PLi and Merlin images. Now OpenATV & Merlin.
On Duo2 I use VTi, ViX, BH and OpenATV images. PLi4 works perfectlly on my Duo2 but only on flash (till now: not Multiboot compatible) - so I can't use it daily.

Could you provide some links please?
My DUO2's are in daily use and I have zero problems. And following a number of forums, I haven't read about any.
