DVB-USB which version is installed?
I have just put a Nova-T 500 dual tuner into a newly installed mythdora 4 box. I also have a standard Nova-T in as well.
I wondered if I need to upgrade the dvb-usb drivers or if the current ones are the latest?
Here is the relevant output from dmesg, if that helps :-

I find it a bit odd that its used the 2 tuners from the Nova-T 500 as 0 and 2, and put the Nova-T as 1, but it all seems to be working. I had ready though that the older drivers were buggy, which is why I am wondering if I need to upgrade them?

The DVB drivers in MythDora
The DVB drivers in MythDora are as of 4/20/07 so they do have some age on them. You can certainly try using a later version but you will need to compile that rather then use the rpm's. I'm sure they have corrected some issues since then.

Hi Dennis,
Hi Dennis,
I have done the following (as root) (from a fresh mythdora 4 install) :-
wget http://www.wi-bw.tfh-wildau.de/~pboettch/home/linux-dvb-firmware/dvb-usb-dib0700-1.10.fw
cp dvb-usb-dib0700-1.10.fw /lib/firmware
yum install mercurial
hg clone http://linuxtv.org/hg/v4l-dvb
cd v4l-dvb
make
make install
Added options dvb-usb-dib0700 force_lna_activation=1 to /etc/modprobe.d/options
After a reboot, the it looks like it must be using the new drivers as I get
dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.10.fw'
in dmesg, which is the new version, so thats good I assume. Oh, and this time round the Nova-T is DVB 0 and the Nova-T 500 is 1 &2. Not sure if this is random, or based on some other criteria.
Anyway, the signal strength is very poor, and seems no be no different now I have added the dvb-usb-dib0700 force_lna_activation=1. Is there anyway I can tell that bit is working? Nothing gets added to the log files.
My Nova-T is showing 23% signal (which I think is inverted, as pulling the aerial lead out is 100%), so thats really 77%. The Nova-T 500 shows 49% and 51% on the different tuners, and the 49% can't get a lock.
Just for completeness sake,
Just for completeness sake, incase somebody else searches for the same problem, I found that If I plug the aerial directly into the Nova-T 500 The signal strength jumps upto about 65%, which is just about acceptable.
When it's connected via the aerial out on the Nova-T it drops to the 50% mark. Using a passive splitter before the 2 cards seems to be fine, and does not degrade the signal more than about 1%.
So I will purchase an amplified splitter, and I'm sure all will be fine.
I have no idea why the passive out from the original Nova-T is degrading the signal so much, it seemed to be able to drive a second nova-T that I used to have in the system just fine.
