This is not a cx18-firmware bug. Its either a kernel bug or a hal/udev/devicekit/whatever bug, if the device /dev/video0 is present, but can't be opened by a non-root user. You might also have better luck rebooting after installing the firmware, as perhaps the device permissions will be correct after you login with the firmware already in place, not sure, just a theory.

Also... does this device have a hardware mpeg2 encoder? If so, tvtime won't work with it, no matter what you do. At least, as far as I know, tvtime only supports raw video, it doesn't support devices with hardware encoders.

Comment 3 Jarod Wilson 2009-09-17 14:11:43 UTC

Device does indeed have a hardware mepg2 encoder, and is not supported by tvtime.
