Based on the linuxtv.org web pages and the mailinglists I was under the
impression that the TT DVB-C card would work with the linux driver.
Yesterday it occurred to me that most DVB-C users on the list probably
have a Siemens card and thus the problems with TT's card have not been
found out earlier.
!! Is there anyone on the list who has a TT DVB-C card working with the
linuxtv.org DVB driver !!
My card has a "C-rev2.1" sticker on it. This is the same card that is
identified as DVB-S by the linuxtv.org driver.

I understand that its hardand frustrating to support cards that you do not
personally have access to.

IMHO if you claim to develop a driver a driver which supports e.g. Siemens
DVB-C cards, then you should at least try to support new card versions.
Especially since from the consumers point of view the card revisions
aren't really that visible. That is, people don't know automatically which
card revision they are buying. But since this is open source software, I
understand that you cannot do everything. Come to think of it, I'm not
sure whether you claim to support any card...
I'm just pissed at the moment since I was under the impression (my
mistake) that the driver would work with all TT-based DVB cards. Now you
are telling me that the driver will work with TT-based rev1.3 DVB-S cards
only. Interworking with other cards will be an accident.

That's a pitty since I'd assume that the user group will probably not grow
from this in the future. I'm assuming that rev1.3 cards aren't available
TT claims to have a linux driver for their cards on request. I'll email
them and see what they answer. If the driver is crap, we could all (or at
least the TT DVB-C card owners) send an email to TT requesting them to
support Ralph in the driver development.
Please note, that I'm very interested in getting the driver to support
TT DVB-C cards, so I'd be very interested and willing to help in this
