I played with linux many years ago (stopped around KDE first release) so I not unfamiliar with the file system but many things have changed since then. I recently wanted to build a media center around MythTv and have followed the wilsonet HOWTO. I bought an DVB-T card Cinergy 1400-T which is supported in Kernel.
MythTv run fine if I start mythbackend as root but if I get it started on boot as sugested in HOWTO or the user mythtv start it manually then i get following message "DVB#0 ERROR - Opening DVB frontend device failed. (13) Permission denied".
Permission to /dev/dvb and /dev/dvb/adapter0 are set too drwxr-xr-x 2 root root 120 so I figured that was the problem but if I do a chown mythtv.root /dev/dvb* it doesnt change a thing.
Another problem is I tried figure out udev to put dvb into a video group so I easier could control rights but any attemt I made failed. I have created a file named /etc/udev/rules.d/10-dvb.rules with a line KERNEL="dvb", GROUP="video". but it doesnt seem to have any effect.
I hope anyone have sugestions to where I find a solution to my problems because I am stucked with my knowledge level.
