[mythtv-users] Permission issue with /dev/video0, HDPVR

[Mark]

Setting up a HDPVR, debian 10.  Kernal modules installed fine.

mark at odin:~$ dmesg | grep hdpvr
[   13.067722] hdpvr 5-2:1.0: firmware version 0xf dated Mar 11 2009

mark at odin:~$ ls -al /dev/video0
crw-rw----+ 1 root video 81, 0 Aug 17 07:22 /dev/video0

I am user of groups video

mark at odin:~$ id mark
uid=1000(mark) gid=1000(mark) 
groups=1000(mark),24(cdrom),25(floppy),27(sudo),29(audio),30(dip),44(video),46(plugdev),109(netdev),112(bluetooth),116(lpadmin),117(scanner),998(docker)

mark at odin:~$ cat /dev/video0 > test.ts
bash: test.ts: Permission denied

Only way to get capture is to run as root, not even sudo will do it.  I 
can chmod 777 /dev/video0, but even then it won't capture as user.

I played around with access control lists, but also did not work.

Any ideas?

I've never had problems like this before.  New hardware, new install.
