I have an old 3B (not 3B+) that was doing nothing,
so I thought I would try it. <br>
<br>
I loaded Buster and then the Mythtv light. No tweaks
no MPG license. The GUI ran painfully slowly each
screen change rendered incrementally. The setup
video even in standard was very choppy. <br>
<br>
Is there anything I can do to make this usable, or
is a 3B just totally inadequate. <br>

It should not be that bad. Did you follow the guide in
the wiki? <br>

This version is run from command line so you should
set up the system to start in command line mode. <br>

<div>This was discussed on the mythtv forum (link below). But
here is a quick summary.</div>
<div>use this command:</div>
<div> QT_QPA_EGLFS_ALWAYS_SET_MODE="1" QT_QPA_PLATFORM=eglfs
QT_QPA_EGLFS_KMS_CONFIG=./pi_mythfrontend.json mythfrontend
--noupnp --logpath /tmp</div>
<div><br>
</div>
<div>and create ./pi_mythfrontend.json:</div>

<p>I am no longer using the raspberry pi for watching, and the wiki
seems to be out of date. Would you like to update the wiki to the
latest information? Let me know if you want to do that and I can
set you up with a user id.</p>
<p>Peter</p></div></blockquote><div><br></div><div>Writing up something is the easy part, I've done that on the MythTV forum and on my blog (which needs updating also). However, the last time I tried to update a Wiki was impossible because it wasn't WYSIWYG and you had to know a lot of arcane markup codes. Too much like using word processors back in the DOS days, and I mean IBM System 360 DOS and not IBM PC DOS.. Is there a way to take the wiki page into a real editor and fix it and then put it back into the wiki?</div><div><br></div><div>Jim A</div><div><br></div></div></div>
