I upgraded to a 1TB HDD (from DVRupgrade) and I lost only HBO, so I called comcast and during their many efforts to fix my HBO problem things have only gotten worse and worse. I went from loosing just HBO to loosing all my digital cable channels. After 12+ calls (5-6 hours) over two weeks Comcast has offically told me they have no idea why I can't get digital cable any longer. The only options they have given me is to get their cable box or drop digital cable. Any suggestions on what I can do/say to help Comcast figure out what is wrong.
