Indeed, this makes sense.

If id 0x13c2/0x1004 is a full-featured card, we have to change the 
table entry in saa7146_core.c:
...
static struct card_info ttbc   = { DVB_CARD_TT_BUDGET,    "TT-Budget/WinTV-NOVA-C  PCI" };
                                   ^^^^^^^^^^^^^^^^^^
{ PHILIPS_SAA7146, 0x13c2, 0x1004, CARD_INFO ttbc },
...
Right now it is just a budget card. 

Due to the
        if (av7110->saa->card_type==DVB_CARD_TT_SIEMENS) {
statement, the DVB-C code will never be executed for this id.

Perhaps Andreas should double-check whether this id is really correct.
IIRC he reported that it works now. So the id must be wrong...

Thx, I just wanted to be sure.
