Comcast Digital Voice infrastructure?

[Scott Ehrlich]

Thanks to all who responded.  They told me they are going with Comcast. 
RCN had switched them to DVR boxes (they have been with RCN for 7 years). 
With the digital non-DVR boxes, they never had problems.  With the new 
boxes, they have problems, went some rounds with RCN, and in the end, RCN 
claims their tv is at fault which, until RCN switched the boxes, their tv 
worked fine.  So, they are opting to go with Comcast and hope for better 
service.
