All very interesting pheonix - thanks for the explanation. I'm keen to learn more ... so I have a few more questions.

If I ssh onto my GB Quad Plus ans run:
Code:
> modinfo dvb
filename:       /lib/modules/3.14.2/extra/dvb.ko
license:        GPL
description:    BCM7XXX DVB Driver (michael@gigablue)
version:        20141020154934-14.2
depends:
vermagic:       3.14.2 SMP mod_unload BMIPS 32BIT
parm:           config:string
So from the version the driver date is the 20-oct-2014
That corresponds with the driver date that openvix reports (menu->information->about->Drivers) ... I was always curious where that date came from!

You mentioned the driver for the GB Quad plus came from here:
http://archiv.openmips.com/
However, the date on that driver on that link is 31-jul-2014! So http://archiv.openmips.com/ is clearly not the location of the current driver. Is that right?

If I look here however:
http://gigablue-support.com/
and click "openMips 4.2 Firmware Download", I get to here:
http://image.openmips.com/4.2/index.php?open=gbquadplus
I can see there are more frequent released of openmips.
If I download the latest and unzip the dvb.ko, I can see it has a size of 16,492,687 bytes. The size of the dvb.ko on my own GB Quad Plus is: 11,060,791 byes.
Shouldn't those files be the same size if they were both the same version of the driver?

Thanks for taking the time to help out.
