Several Days of Problems with Bravo and SyFy channels

For the past few days, I have been seeing audio dropouts (no sound), video freezes and the occasional Colored-Vertical bars test pattern. Other posts have indicated that these symptoms, especially the colored bars, have to do with the source itself - the networks. Has anyone else seen this? It is quite possible this is happening on other channels, but these two are ones that are watched a lot in my household.
