Hello,

Avermedia released binary-only drivers for Linux for they TV tuner
card "AVerTV Hybrid+FM Cardbus (E506R)":
http://www.avermedia.com/cgi-bin/support_driverbympdpro.asp?category=TV%20Cardbus&category2=Hybrid&proname=17&modelno=E506R.
Their driver is named saa713x.

This card uses saa7134 chip, and (GPL-licensed) driver for this chip
is in v4l Linux kernel, named saa7134. I tried to make the saa7134
work with mentioned card, and found the suspicious similarity between
exported symbols of saa713x and saa7134. I checked the implementation
of couple of simple functions in drivers (comparing assembly code),
and found that they are identical.

Seems to be GPL violation by Avermedia.

Please, keep both mailing lists in CC.
