I just got a "Voice Mail" from Comcast stating that tonight starting at 10 PM the change will start.
I looked at the web site ( link provided by wdwms / TY

)
It states that if you have HDMI with Optical out for 5.1 , it might not work

That is how I have mine set up , BUT , I have the newer "Cisco" black box , so I guess I will know tomorrow.
Man , if I lose my 5.1 that is going to sux , it did say that a fix is in the works , but no time frame.
Also :
What about the new HD channels ??????
Have they forgot about them ?
Caller ID on TV screen ?
Londonderry feed still needs a lot of work , I think.
___BUT___ who knows maybe we will be surprised with all kinds of greatness !
___OR____ Disappointed with a box that doesn`t even work.
O__well , that`s Comcast !
