So I'm out of luck then. If I try to use xawtv without xv, I can't change channels or anything, I get lots of errors and it finally segfaults when I try to change channel: ioctl: VIDIOC_G_TUNER(cmd=0xc090561d): Invalid argument ioctl: VIDIOC_G_TUNER(cmd=0xc090561d): Invalid argument ioctl: VIDIOC_S_TUNER(cmd=0x4090561e): Invalid argument Segmentation fault The errors appear randomly while viewing. -Erik _______________________________________________ Video4linux-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/video4linux-list
