I have a VIP211 receiver and the audio is connected to my Yamaha receiver using an optical cable. Ever since the software upgrade from 268 to 340/41, all the 5.1 audio on all E* HD channels (including my OTA locals) keeps cutting in and out. The audio on SD is fine. The worst channel is STARZHD, channel 9435. I am watching Chronicles of Narnia and it's unwatchable. I called E* tech support and they said that there is a known software issue with the audio and that they are working on it. Their usual solution to everything is to reset the receiver. That does not solve anything. Is anyone else experiencing this problem?
