'using pic to control a vcr'

Hi to all engineers in this list.

I am a middle  of  making a vcr control unit using pic almost done. the
idea of this is to
turn the vcr on off play stop and more automatically .since I
couldn't find ir remote information about samsung to use UART and I
was not smart enough to capture ir  code I decided to drive them
from switches like pressing buttons. switches are connected together
in multiplexed method that means each switch when you press it
doesn't ground the only access i have is switches. my question is
to press a button electronically should i use optoisolater or can I use
electronic analog switch like 4066. any recommendations ?


Andre                         thank you very much.

I was planning doing something similar - in order to make a bank of
VCR's record sequentially. I was going to use 4066's to drive the
multiplexed inputs.
