Some have reported having problems with 5.1 and 9.1. Comcast PLAYED with the channels on August 23rd, in addition to many other times, but they have evidently used some new software (although they aren't admitting to it) that has messed things up for some tuners. You can try re-scanning, or Auto Program, and see if that solves the problem. Also, have you looked elsewhere for 5.1? ...maybe 15.2.
Good luck.
The 80.+s are still missing...thanks Comcast
