[mythtv-users] TV Output

I already soldered the RGB pin; that works.  But how do you connect the
other pin.  What resistor did you use?  It says input impedance > 10 kOhm.
 Now, what do I use to get from 12V to 6V?  Simply use 10 kOhm?

My tv is on auto detect, so it will do 4:3 tv in 16:9 subtitle zoom mode
and will do 16:9 in true 16:9 if it's detected.  It will detect a tv
transmission in 16:9 and a 16:9 dvd if my dvd player is used, but not if I
play the dvd on mythtv.

Kind regards,

Mark
