For info
I have test RC silver and black with new dvb modules
and I can say I'm not at all happy with the work of the same.
I think now you have extend time to the pressure on the button
for short and long pressure ,to compensate the problem with
longbutton press.
Of course this solution have reduced sensitivity to remote control
and have reduce the speed and sensitivity of DM500HD on the RC commands.
Of course this solution is not good for a remote for a longer period
shorter life.
Especially bad is reaction of the receiver on a short press of a button
with silver remote and old drivers this working perfect with old drivers.
I hope I'm wrong but in my tests, it is the result.
