우분투 처음 쓰는 사용자입니다.
TVTIME을 설치하고 사운드는 aux단자에서 외부선을 연결하니 영상과 소리도 잘 나옵니다.
그런데 CABLE TV채널이 다 잡히지 않고 몇개만 잡힙니다.
뭐가 문제인지 잘 모르겠네요.
그리고 아래의 bttv.modprobe와 rc.local의 각각의 코드 의미를 알 수 없을까요?
sudo gedit /etc/modprobe.d/bttv.modprobe
alias char-major-81 bttv
options bttv card=43 gbuffers=4 tuner=2
alias char-major-81 videodev
options msp3400 mixer=1
=========================================
sudo gedit /etc/rc.local
#!/bin/sh -e
rc.local
This script is executed at the end of each multiuser runlevel.
Make sure that the script will "exit 0" on success or any other

By default this script does nothing.
exit 0
modprobe bttv card=43
