Great job and the image works very well for most daily use!
Some suggestions for future improvements:
-The IPTV I tried via JediMaker has sound and video unsynced by about 0.5-1 sec. Since it works OK on my other receiver I guess it could be due to some player issues ?
-No sound on some media files. Typically resulting in "Gstreamer plugin AC-3 (ATSC A/52) decoder not available" or "Gstreamer plugin E-AC-3 (ATSC A/52B) decoder not available". Happens on newer x265 or files with Atmos audio.
-The standby on/off button only turns the screen black, the HDMI output is still there and the LED remains strong.
-Switch resolution between HD and 4K option! (No module named VideoHardware). Maybe this has already been fixed?
-Perhaps some basic stuff such as ftp/nano could be included in the image ?
-The new remote has fewer buttons (e.g. no "subtitle" button), so some way to reassign buttons would be nice.
Thanks for the great work!
