Seeing this also on my mythbox's RV350, within the menu buttons of gnome, xvid
movies, and dvd's.
Using test images from here: http://www.lagom.nl/lcd-test/ (even thou they are
lcd specfic, they do show up on my ntsc tv.)
It'll fail the White Saturation Test 254
Inversion test 6a & 6b
and the bottom two right in the response-time test.
Found a little note here on NTSC signals and the results with highly saturated
colors.. https://computing.llnl.gov/vis/guidelines.shtml
Which I believe we are all seeing...
And a note about making images NTSC complaint, they recommend color values
within 16 to 235 : http://people.csail.mit.edu/tbuehler/video/titles.html
Can't really test at the moment, mythbox is busy recording and the spare test
rig is down, but there looks to be gain controls for Y and UV in radeon_tv.c
located here:
717 save->tv_gain_limit_settings = (0x17f << RADEON_UV_GAIN_LIMIT_SHIFT) |
718 (0x5ff << RADEON_Y_GAIN_LIMIT_SHIFT);
724 save->tv_linear_gain_settings = (0x100 << RADEON_UV_GAIN_SHIFT) |
725 (0x100 << RADEON_Y_GAIN_SHIFT);
Regards,
Robert
