The QO-100 beacon has a timing problem at the moment, so the picture on MPlayer is jerky. Neither of the other players (VLC or omxPlayer) have ever been able to decode the beacon video; it is something to do with the data structure produced by the beacon encoder.
I have reported the beacon timing problem to AMSAT-DL; the behaviour that you are seeing on the Portsdown is exactly what I would expect.
I can confirm I can get sometimes a very jerky image on MPlayer and audio the the others.
I was able to decode signals at 333 and 250 (h.264 and h.265) with VLC and OMXPlayer only.
To upgrade, go to Menu 3, Check for Update, and make sure that you are on the latest version. If not, you do need to update to the latest production version. Once you have dioone that, the "Dev Update" button wil appear. Select that, confirm and sit back and cross your fingers.
Preview of what to expect below.
Thanks to Phil M0DNY for developing the fonts package and to Colin G4EML for prompting me to get on with it!

Looks excellent, definitely a worthwhile improvement!
I have a Lime Mini, Pluto, Minitiouner and RTL-SDR dongle so can plod through as many facilities as you think it's worth testing. Are there functions which are known not to be working or any tests you think may be particularly useful?

Pleased that it worked for you. As for testing - just play with it and try to make it do what's useful for you. I'm particularly interested in logic faults in the menus, or any captions that are misplaced or could be improved.
I'm not sure if Ugly is supposed to be working yet but, for what it's worth, I found this...
Switched from Langstone to Portsdown
Selected Preset 4 - 437-Ugly - Source TestCard
Went into transmit ok and showed testcard on 7" screen
Started transmit again. This time no picture - TX button red.
Pressed TX again - button went back to blue.
Switched to Langstone
Pi crashed and needed a power cycle.
Tried the same again but with Source = PiScreen
Apologies if you've already said somewhere that Ugly doesn't yet work.
LongMynd seems to work well as mentioned before. I was getting some proper hifi music and a hi-def test card from an Italian station about 15 minutes ago.

All best John
P.s yes please for tonight and I'll monitor AW
I had meant to delete the "Portsdown" [filter-modulator board] and "Ugly" Output buttons as neither of these will work due to design changes in the Raspberry Pi 4. Very experimental on transmit at the moment (Lime or DATV Express (?) only).
I do not intend to do any work on the "Portsdown" [filter-modulator board] and "Ugly" modes. These are well supported by the Raspberry Pi 3 and Portsdown Buster 2020.
The new buttons / text look great.
Testing today to see what was functional.
Could not get IPTS monitor working. Is this on the known issue list?
tried it on PORTSDOWN 2020 to check it worked there.
Many thanks to you and Phil for the latest update.
