Before posting, I have been trying to quantify the issue. I currently have the dropped audio, WITHOUT any dropped packets from a different channel, with 'jumpy' video. Does that imply the dropped packets may not be the issue ??
I don't think so. If the video is choppy, then there's something funky about that channel that the Roku doesn't like. I'm convinced the dropped TS packets are responsible for the dropped audio on your other problem channel.
