Comment 1 Juan Pedro Paredes Caballero 2006-01-16 08:33:25 UTC 
in drivers/media/dvb/bt8xx/bt878.c  
the probe method  
bt878_probe(struct pci_dev *dev,const struct pci_device_id *pci_id)  
  
This method does not take care about subvendor and subdevice to enable pci.  
  
Why not have a enabled or disabled param?  
 
I will try to force dvb-bt878 probe error to KWorld device

Comment 6 Juan Pedro Paredes Caballero 2006-01-17 00:08:44 UTC 
Due to a audiomux misconfig of Kworld TV card (next bttv-cards.c  in my todo  
bug list :P), I can't get sound fom this card (but snd_bt87x now is detected  
and I can use it, no sound, but is detected and works)  
  
I change this card by a Pixelview TV card bttv.card=78 to bttv.card=70. 
 
Now I get sound from snd_bt87x 
  
See attach.  
  
With 'Really, really dirty fix'  the DVB card works well and the TV card works  
well, now my mythtv is complete :)
