[mythtv-users] xorg.conf & 27" analog TV

[Dan Littlejohn]

I have got my tv out display working pretty well, but it still has an
odd problem that I cannot solve.

When I am in the window manager (evilWM) or Myth the display has a pin
cushion effect, which I expect is because I have a 10 year old analog
TV.  However, what I am concerned about is that when I am using just
the window manager, about a minute after X starts, the display begins
to have large blobs on the screen and it will lock up.  It looks like
the screen is being burnt which is obviously no good.  I have tried
different resolutions and other settings, but the problem persists.  I
have not been able to find out any specs on my TV.  It is a 27
Magnavox TX2753 C202 so I have just been using the standard ones.

Here is my xorg.conf.  Anyone have any tips?

Thanks;
Dan
