Comcast Channel 104

My wife and I were watching "Desperate Housewives" in high-def. Wonderful, except that the audio kept skipping. So, at the end of the show when it became unbearable, I called Comcast. Lo-and-behold, a person answered the phone and, the second I said something about skipping audio, asked "Channel 104?" I allowed as to how it was, indeed, channel 104. She informed me that they were working on it. No ETA on a solution. She did apologize. But sheesh. How hard is this stuff? I mean, it's not like it's an OS or anything. :-)
