TvTime


Hi all!

I am trying to run tvtime (tv capture app) on Fedora, but it says

videoinput: Cannot open capture device /dev/video0: No such device

I checked the /dev dir video0 is sitting there. Anyone know a fix for that?

Thank you!

Did you try running as root?
You may need to change some permissions

Be advised, I'm running Slack 9.1 (kernel 2.4.22) with i2c and v4l compiled in. (as mods)
Also ignore the "using 8 buffers" in dmesg, it's my own doing.
