Hello
I have a problem with Qbox 2. I've just bougth it and installed without any problem. Card is recognized properly, firmware loads, devices are available and almost works.
Almost, because I have problem with most channels.
When I use szap-s2 it takes about 30s to tune any channel, but I can tune channel. Hovewer when I try to watch or record it (I use VDR) it sometimes work, and sometimes can't tune.
I use dual setup - I have connected to the same dish traditional tuner and Qbox card. Tuner works ok (sometimes there are artifacts when a weather is bad), i've exchanged both outputs to eliminate that it's cable problem. I suspect that Qbox card is much less sensitive and so there are problems with signal strength.
Hovewer I don't know how to read properly signal strength and snr. If it's hex encoded - it seems signal is quite qood.
Recorded streams has errors.
It's my 4 card and all of previous 3 different had similair problem, so there is possibility that my computer is somehow broken.
I use the latest driver 12814 on Debian testing with 3.5 kernel.
I can say that README_TBS_QBOX2_UBUNTU is incomplete: it say to put dvb-usb-tbsqbox-id5920.fw while my card need dvb-usb-tbsqbox-id5928.fw, It also doesn't say anything about dvb-fe-cx24116.fw
Here is output of szap-s2:

Edit. I would like to add kern.log attachment but it's impossible and it's to long to post it in the message body
