After a recent update (fedora 34) mythbackend failed to show any card.
Short story:
	crw-rw----+ 1 root rtlsdr 212,  3 Jun 20 23:10 /dev/dvb/adapter0/frontend0
so user mythtv cannot open it. chmod fixed it, and I added this to my startup scripts.

Was this an intended change? This update brought in
	mythtv-backend-31.0-17.147.20210421git05c16580e1.fc34.x86_64
and friends as well as
	kernel-5.12.11-300.fc34.x86_64
	rtl-sdr-0.6.0-9.fc34.x86_64

The group rtlsdr is new:
	Jun 20 22:43:17 e7 groupadd[1678612]: group added to /etc/group: name=rtlsdr, GID=440
	Jun 20 22:43:17 e7 groupadd[1678612]: group added to /etc/gshadow: name=rtlsdr
	Jun 20 22:43:17 e7 groupadd[1678612]: new group: name=rtlsdr, GID=440

Is there a possible conflict?
Should user mythtv be added to the new group?
