i need old firmware version 1010N-1003N-1005N-1002N
for DVR Avtech kpd674zb-c
When I was in the past, used this version (1010) then the DVR works very best
But when I've updated to version (in 1012 and 1013 and 1015 and 1017) I found that all of these versions are slow when using Option Playback (specially when I use brogress bar) I feel a slowdown in response
