hello
so unfortunate from you DMM guys that you dont pay attention to NA customers
anyway, the actual DM800x tuner does not support Turbo-Fec 8PSK and Turbo-Fec QPSK which are used by both Dish network and BellExpressView for their HD channels
therefore DM800s becomes useless and cant get those HD channels
there is a genpix tuner called Skywalker-1 that can tune those 2 modulations and many other, it's usb tuner and designed to be a DVB-S card
Genpix tried to develop beta drivers, he succeeded but the channels are almost unwatchable, with high cpu usage and stuttering image followed by sound desynchronization
here is his last statement about the situation:
ZitatAlles anzeigenentire line of Genpix DVB-s cards was designed for PC use, and existed way before DM800 emerged.
The only reason why SkyWalker-1 is working (kinda) with DM800 is because this receiver is a PC with USB 2.0 interface an running Linux.
The only restriction with DM800: its tuner driver architecture is a closed source. And one has to use exposed virtual driver interface (which is closed source, as well) to connect third party tuners.
I have an impression that virtual driver interface is a bottleneck right now (in terms of CPU load). Have you tried to use it with any other USB tuner? I bet, you will get similar results as with SkyWalker-1.
I'm trying to go a bit around it (to avoid pumping data across the kernel memory map <-> user space memory map border, twice by the way). But it would save just a little bit of CPU time: data pumping is cheap (in terms of CPU time).
As expected, I don't see much improvement (on top of that I have to find a bug - I have a memory leak now
Maybe, if DM driver architecture were an open source it would be much easier to support third party tuners.
Don't you think so?
But Dream Multimedia is not interested in that
i think it's in your benefit to help us out, people will not buy a DM HD receiver if they will not get HD channels, if you add support or you make the tuner architecture open source, NA FTA market will go towards DM
Im pertty sure If Euro went 8psk, the driver would be available in minutes...LOL
Thx and i hope i will get an answer
