ok, so the problem, whatever it was, seemed to have fixed itself once I installed PEP3.

I'm back to using PEP2 tho since pep3 is only in beta.

I'm still building my setup file to match my equipment. But progress is finally being made.

I just made the purchase of the larger panel unit from AU-eBay. Cost me about $400 UDS but now I also have a tsu 9800 unit. Seems like it was brand new old stock. The shipping speed was insanely good too. Got it to my house in less than 7 days.

My home theater system is not overloaded with devices. It's a nice quality system.

Marantz AV7720mkii pre-pro - most IR codes work well, some are fussy.
Adcom 2535 4 channel external amps (no control needed).
Apple TV4k - found hex codes here that seem to be working on it.
Panosonicc UDH UB820 - found hex codes here that seem to be working on it.
PS3 - just need to flip to that HDMI in. all other controllers via rf controller.
KDLinks media streamer - finally got all the codes to learn in black instead of blue. Looking for discreet power on and off but toggle works for now.
Bluetooth - got the Marantz IR code working on the pronto pro.
LGTV - most codes found here are working. Ill manually add the missing ones.

Loving that I can add Marantz sound buttons into my other pages for direct access to buttons like 'stereo" "doby" 'DTS" EQ, etc.

I also have a 9400 RF unit. I'll figure that out after I get everything else debugged.

Once I'm happy, Id love for you to go over my code to suggest improvements.
