[mythtvnz] mythtvnz Digest, Vol 178, Issue 3

[Mark van Dijk]

Just a quick update on my recent issues where TV3 (and other channels on
the mux) stopped working a few weeks ago, and re-scanning was not able to
find them.  As suggested by Stephen/Simon, the problem was related to my
old version of MythTv (0.31).

I have updated my machine to Ubuntu 24.04 (LTS).  I tried (and failed) to
update MythTV (had some MySQL issues) - so had to completely purge
mysql/mythtv and reinstall those from scratch (no big deal - nothing of
importance lost).  Now running MythTV v35.  TV3 channel now working just
fine.  Everything pretty much back to normal.

One minor issue i've noticed, after some time of not using my MythTV
machine, the HDMI signal stops (screen blank?  power saving?  don't
know...).  Problem is, it does not come back when i try to use MythTV - TV
just says 'no-signal'.  I have to press <ctrl>-<alt>-F3 and then
<ctrl>-<alt>-F2 to get the screen working again.  Oddly, this only seems to
happen when i run my TV at full 4K resolution.  If i run at 1080, then the
MythTV screen always appears instantly when i switch back to it...    I'm
running the nVidia 550 driver.

I wonder if anyone else has noticed this?
