Titolo: Problemi Frame Grabber

Ciao a tutti, sto cercando di configurare un frame grabber su una
RedHat 7.3 con kernel 2.4.24. dopo aver installato il software
i2c-2.8.7, ed essermi documentato su quali moduli utilizzare per il
mio Frame Grabber (Multimedia video controller: Brooktree Corporation
Bt878 Video Capture (rev 11) sono arrivato alla conclusione che devo
caricare il modulo bttv.o, quando vado a fare modprobe bttv ottengo un
segmentation fault ed i log riportano quanto segue:

appena provo ad aprire xawtv mi dice che non trova il device
/dev/video0.
Qualcuno saprebbe aiutarmi?
Grazi anticipatamente

A me e' capitato con le schede nvidia che hanno l'uscita s-video, prova ad
usare xawtv -c /dev/vide0 oppure 1 .
