How to enable DV-in, briefly

Change the following data:

		MV20			MV200/MV10
PG	BK	ADDR	DT old	DT new	ADDR	DT old	DT new
6	4	0030	18	08	EP15	18	08
		0094	42	62	EP60	c2	e2

How to do it, in more detail

So you have removed the front cover, printed out a listing of the relevant keys of the RC. Further, you have removed the tape, and switched on the camera in the PLAY mode.

This is for the MV20, the MV200/MV10 are just slightly different, as you can see in the table above.

• Push the E1 button, you see a funny number appear; push it again and you'll see

    PG  BK  MD  ADDR  DT  ST
     4   0  RD  0000  1F
                   00011111
  

• Push button A1 (START/STOP) twice, until the number under PG is 6.
• Push button C2 (four times) until the number under BK is 4.
• Push button G4 (FF) (48 times) until the number under ADDR is 0030.
• The number under DT should be 18.
• Push button B4, RD under MD should change into WR.
• Push button H3 (STOP) (16 times) until the number under DT is 08.
• Check that you now have PG=6, BK=4, ADDR=0030, DT=08, if not: push button B4 to leave the WRite mode, and correct.
• If it's correct, push button I2 (PAUSE) to store the data, a * appears under ST.
• Push button G4 (FF) (100 times) until the number under ADDR is 0094.
• The number under DT should be 42.
• Push button B4, RD under MD should change into WR.
• Push button G3 (PLAY) (32 times) until the number under DT is 62.
  At some values the screen will be rolling, just ignore that and continue.
• Check that you now have PG=6, BK=4, ADDR=0094, DT=62, if not: push button B4 to leave the WRite mode, and correct.
• If it's correct, push button I2 (PAUSE) to store the data, a * appears under ST.
• Push button E1 to leave service mode.

What do these 2 bytes do

Address 30 controls the DV-in status, it allows the camera to accept the data from the DV cable. Address 94 controls the ability of the camera to accept RECORD commands from either the remote or DV cable.

How to reverse these changes

Simple: reverse the entire procedure. There's no `restore factory settings' I think.
