No, at least mine look like:

drwxr-xr-x 2 root root 120 Nov 20 16:33 dvb/adapter0/
drwxr-xr-x 2 root root 120 Nov 20 16:33 dvb/adapter1/

You reported:

1. When you ran mythtv-setup, were you running the program as user mythtv?
    If not, you should add yourself to the video group too. But, it's better
    to run mythtv-setup as the mythtv user.

2. Are you sure you loaded the correct version of the firmware? See:

Also, my minor device numbers are different, except net0. I don't
have the card you do, so I can't say that it's wrong, just different.
