Hi all,

I would like to report a bug for openHDF 5.5 in combination with 2 x CXD1981 DVB-C tuners on Dreambox 7020HD:

If I do a cablescan openHDF only detects channels in the range of 100-799 MHz. My cable operator however does also have some channels in the 800-858 MHz range which is still compliant to DVB-C standard.
Why doesn't openHDF detects those channels? Could you investigate if this is a bug and release a fix? Thanks!

Also I would like to do a suggestion: during channel switch times the current image is still displayed on the screen and lookes like it freezes which isn't the case ofcourse.
Could you guys show a black screen during channel changing times? This is what most receivers do. Thank you!

Keep up the great work!

Regards,
Retrofan

I also found this on the internet:

New drivers dreambox-dvb-modules_2.6.18-7.4-20120202 (forums.openpli.org/topic/22105…modules-2618-74-20120202/)

update dreambox hardware drivers
- cxd1981(hybrid DVB-C/-T) increased max. frequency to 900Mhz
- cxd1981(hybrid DVB-T) fixed ineffective 5V for active antennas after mode change

dreamboxupdate.com/opendreambo…-20120209-r0_dm7020hd.ipk

and probably latest versions:
stable: dreamboxupdate.com/opendreambo…0131228-r7.0_dm7020hd.ipk
beta: dreamboxupdate.com/opendreambo…0161019-r7.0_dm7020hd.ipk

Could you guys please increase the maximum DVB-C frequency to 900 MHz for CXD1981 tuner (hybrid DVB-C/-T), or at least 862 MHz as fix in openHDF?
Ofcourse, the cablescan feature must stay.

Can I install this IPK manually without problems, or isn't it compatible with openHDF?

@Koivo: thanks, that's much appreciated! Please update this topic as soon as you did the necessary changes.
The mentioned beta is from 2016 and the one with first support for 900MHz from 2012.
Can I try those IPK with OpenHDF or do a need a special version?

Thanks!

@Koivo: How can I turn the screen black during channel change? Could you be more precise how this option is called in openHDF? Thank you.

@Koivo: thanks! Does this one also has the fix for CXD1981 tuner? (support for 800-862 Mhz frequencies) Otherwise I think I will wait for that build.

By the way, with OpenHDF #228 I got an error when I want to reboot my Dreambox 7020HD.
Here is the crash log. Maybe you can investigate this as well? Thanks again!

This always occur when I reboot the 7020HD.

What changes does it have?

I changed the LG hybridtuner CXD1981 for a Philips CU1216Mk3 from DM8000 and no problems anymore! So the tuner was the problem. Strange, as the LG is the default tuner for 7020HD and 7080HD.
