As far as the 596/568 things go, RTFM...

1) The "1C" in the 596's OSD menu is used for setting up each source if you are using the 596 as a controller, ie. if the 596 is managing all of the comms, and you select the CD source, the 596 will send comms messages with category 1C (ie. CD players). As you are using a 568, this should be controller and the Source Config options in 596 are irrelevant.

2) Set the '800 present' option in the PC config for 568- this sends normal arrow keys to the DVD player, and takes function-arrow keys into the 568 for presets, etc. If you don't set this, function-arrow keys should go to your 596.

3) The display on the 568 will tell you what signal is coming in on the wire, in this case 44k is correct. The 568 can upsample, putting out 88k, but seeing as this is an output, it is not listed on the 'input parameters' display.

4) Dunno.

5) In the 596 "Meridian setup", try setting Controller to "no". If that doesn't work, try contacting Meridian Service...

6) Dunno.


Hope this helps,

Simon.
