Don't know if this is the same problem others have reported on this list
(poor saturation), but I've tried everything suggested on these other
topics with no luck.
I have a house antenna going to a splitter which goes to my TV and my
MythTV box with PVR-150. I put the TV in PIP mode so can easily switch
between live TV and the output from the PVR-150. The problem is the output
from the PVR-150 is dull and lifeless. Whites show up as dull and grey and
appear over saturated (no details in white objects seen, just all white
which is really more grey than white). So an object like a piece of white
paper shows up grey and over saturated so nothing on the paper is visible.
Increasing the brightness or contrast (via ivtvctl or any other method)
only results in washing out the whites even more and it doesn't help with
the other colors.
I've bypassed mythtv by running:
cat /dev/video0 | xine -pf stdin:/
I've tried the antenna port with a Radio Shack signal amp with no help.
I've tried composite video input (from my VCR) and no change so this
appears to be something with the PVR-150 itself.
I know that the video card output to my TV is OK as I can play a DVD via
mythtv and the same DVD on my VCR (at the same time) and using PIP I see
that the output is the same (or virtually the same).
Any thoughts and/or suggestions?
