Hello Mat,
Answered this one before, but it seems to have been lost during the server failure...
I do have a BV7-23 MK I (Type 9311) and had it updated some months ago. They "flashed" some SW into the BV through a Laptop and had some chips changed.
Now DVD service menu shows the "BLOCK SENSITOUCH" thing.
monitor information says:
AP SW 6.31
IOP SW 22.0
STB TABLE 3.3
STAT DISP 1.0
Never recognized this feature as I don't have the need for it ;-)
Greetings,
hx
