TVDB are updating their site. Their site currently has a number of bugs that have broken the TVDB scraper and any add-on that relies on TVDB data. TVDB are working to rectify the problems.

RPi2 Limited color range? White clipping
#5
I also tried hdmi_mode=16 as per the link. It did not help
Oddly enough, I am not sure 16 is the correct mode/resolution listed.

# tvservice -m DMT
Group DMT has 10 modes:
mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive
mode 6: 640x480 @ 75Hz 4:3, clock:31MHz progressive
mode 9: 800x600 @ 60Hz 4:3, clock:40MHz progressive
mode 10: 800x600 @ 72Hz 4:3, clock:50MHz progressive
mode 11: 800x600 @ 75Hz 4:3, clock:49MHz progressive
mode 16: 1024x768 @ 60Hz 4:3, clock:65MHz progressive
mode 17: 1024x768 @ 70Hz 4:3, clock:75MHz progressive
mode 18: 1024x768 @ 75Hz 4:3, clock:78MHz progressive
mode 28: 1280x800 @ 60Hz 16:10, clock:83MHz progressive
mode 85: 1280x720 @ 60Hz 16:9, clock:74MHz progressive

For some reason, RPi2 is not detecting the proper DMT modes

It sees CEA

# tvservice -m CEA
Group CEA has 12 modes:
mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
mode 5: 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced
(prefer) mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
mode 17: 720x576 @ 50Hz 4:3, clock:27MHz progressive
mode 18: 720x576 @ 50Hz 16:9, clock:27MHz progressive
mode 19: 1280x720 @ 50Hz 16:9, clock:74MHz progressive
mode 20: 1920x1080 @ 50Hz 16:9, clock:74MHz interlaced
mode 31: 1920x1080 @ 50Hz 16:9, clock:148MHz progressive
mode 32: 1920x1080 @ 24Hz 16:9, clock:74MHz progressive

But CEA does not provide full range that I get from other input devices.
And forcing a DMT mode does not correct the color range either
