HI JV,

IŽll check line 21 again, if I remember that code appears on all scrambled channels, Did you fixed video only changing the code on line 21??? Could you post here what you made???
I replaced all zenith code with "NOP" and REV7TD2 is still working.
As I posted here only when "CLRF SPLITCOUNT" was replaced by "ANDWF SPLITCOUNT,0" almost fixed the code, as IŽm not a programmer I dont know how to change FUZZY COUNTER to fix the code.
The 2 level random DC start on line 16 (split-sync)and finish at line 259.You need to remove capacitor AGC hack to see the flickering, cause this DC restore circuit change frame by frame his off-set.
There are 2 NED for normal burst and 4 for DC shifted frame,
PED dont change, so "SPLITCOUNT" make wrong decision for SAInvert.

Happy New Year

Virtuax
