Re: AverTV_A918R (af9035-af9033-tda18218) / patch proposal

[Diorser <diorser@gmx.fr>]

Hello,

Please find below some news for A918R
[details @  
http://www.linuxtv.org/wiki/index.php/AVerMedia_AVerTV_HD_Express_A918R ]

* the patch proposed to automatically load the right modules for A918R  
card is not yet available
=> http://www.mail-archive.com/linux-media@vger.kernel.org/msg56659.html
(I don't exactly know what is missing to make it accepted).
This patch would at least avoid having to modify dvb-usb-ids.h & af9035.c  
each time to test some git updates.

* previously, in December, the signal level detection was fuzzy and not  
reliable.
Now, the reported signal level is strictly at 0000 (good antenna RF signal  
confirmed with other device).

I am aware A918R card is not the most requested one (Express card), but  
that's all I can add in case it can help, even for another card.

Regards.
