I am having an issue of audio dropping when I watch the local CBS affiliate over Comcast. Now I am starting to try to troubleshoot the issue and need some ideas/assistance. I am afraid I am going to be in a situation where Comcast will point its finger at tivo and vice versa. It only seems to be an issue when watching this one CBS channel and on NFL broadcasts. My Setup Family Room Tivo Roamio Pro with Motorola M Stream CC Onkyo AVR connected to Tivo via HDMI Tivo Audio settings = Dolby Digital Basement Tivo Roamio Plus with Motorola M Stream CC Sony AVR connected to Tivo via HDMI Kinivo Switch in-between AVR and Tivo (to stop Slingbox HDCP warning when Tivo is not being watched) I recorded the last 30 minutes or so when the dropouts were occurring. I also watched OTA to see if it was a network issue and no dropouts. When I watch what I recorded from the Tivo I have some random dropouts of audio that I can reproduced with the skip back function and other times the same spot plays fine. It occurs on BOTH tivos. I dumped the recording to mpg with kmttg and it seems to play cleanly, no dropouts. This is using the encoded output with DD signal on my mac mini HTPC and VLC. The network feed on comcast this morning seems to play fine as does the NFC wildcard on a different network. Since both the Pro and Plus seem to have this issue I was wondering if it is a firmware issue. But it is so odd that I only notice it on one channel making me think it is comcast's issue. The issue seems to be associated with dolby digital and one channel. Does anyone have any ideas to help me trouble shoot it? It is so odd and since both Tivo's seem to have the issue and it is only one channel, I don't know what to think. Thanks, filovirus.
