Hi,
  I have two DVB-C card, and I want to install it on one PC.I  added the
foloowing lines in the Makefile in the directory DVB/driver :
 
instwo:
 make
 ( \
 insmod i2c-core.o; \
 insmod videodev.o;  \
 insmod saa7146_core.o ; \
 insmod saa7146_v4l.o;  \
 insmod VES1893.o;  \
 insmod VES1820.o;  \
 insmod dvb.o;   \
 insmod tuner.o;   \
 ifconfig dvb0 192.168.4.1;  \
 ifconfig dvb1 192.168.4.2;  \
 )
 
When i typed  "make instwo" , things seems ok. but when it finished, my
computer seems slow down significantly.I only want to install two DVB-C
card in order to record and play simultanously.
What's the problem? I am using version6.0 of the driver.
 
Best Regards,
