Hi Chuck, I copied this from the MWD7006 manual - I hope it helps.
If your TV is compatible with 525p (480p) progressive scanning and you want to enjoy that high quality picture, you must use Component Video cable connection and progressive scanning mode.
To set the mode, set "PROGRESSIVE" to "ON" in SETUP menu, so that the "P-SCAN" indicator on the front panel lights up.
When "PROGRESSIVE" is "ON", video signals from the unit's VIDEO OUT and S-VIDEO OUT jacks will be distorted or not be output at all.
If your TV is not compatible with progressive scanning, use this unit in interlace mode and set "PROGRESSIVE" to "OFF" either in SETUP menu, or by pressing and holding [PLAY B] on the front of the unit for more than 5 seconds, so that the "P-SCAN" indicator on the front panel lights off.
