[linux-dvb] Re: AverMedia AVerTv Hybrid +FM CardBus drivers

Please write to Avermedia <sales at averm.co.uk> asking for more generic
kernel support.  Apparently they aren't able to release open-source
drivers due to licensing problems with one of their chip
manufacturers.  Linux support clearly isn't a priority (otherwise we'd
have seen many more drivers, a lot sooner after the card was released)
but the fact that Aver is even acknowledging our existence is
encouraging.

I've just fired off an email saying I understand their situation, and
suggesting that they use a system similar to nvidia's, with an
open-source "glue layer" in between the binary driver and the kernel. 
This layer would act as an easily modifiable intermediary between the
driver and the constantly changing kernel.

An idea like that is all very well, but a company will be much more
willing to spend the resources setting it up if it sees lots of
revenue being made back from it.  So if all you people out there think
that AverMedia's products should have more generic Linux support, let
them know about it - and with any luck, sooner or later they will!

Cheers,
Tom :)
