[mythtvnz] DVB drivers location and .zst compression

Hi

I have been seeing minor artifacts (pixellation) , mainly after skipping 
forward during playback.

Hauppauge_WinTV-HVR-2200Back in my installation of MythTV on Xubuntu 
16.04 I saw a similar effect because one piece of firmware  
(nxp7164-2010-03-10.1.fw) for

my Hauppauge_WinTV-HVR-2200 was not in   /lib/firmware/'current kernal'  
, so I was checking the locations of the relevant firmware and I see 
/lib/firmware/'current kernal' no longer

exists.

  The HVR-2200 drivers:   v4l-saa7164-1.0.2.fw      ; 
v4l-saa7164-1.0.3.fw     ;     cp dvb-fe-tda10048-1.0.fw  and    
  nxp7164-2010-03-10.1.fw    are currently all in

/lib/firmware.

The other thing I noticed is that all the firmware is Zstandard 
compressed and the 4 HVR-2200 files with .fw extensions are described in 
the Thunar file manager as "unknown".

Do I need to compress these files and convert them to .fw.zst 
extensions  like all the others or are these ok as is?

Regards
