Periodic audio desync on MHz Choice

[ProfessorChaos]

Hi Comcast community - hoping for some help with a problem.

We watch on-demand programs from MHz Choice with our Xfinity X1. This has worked fine for a year. 

About two weeks ago, we started getting audio problems. About 5-7 minutes into the program, the audio will "rewind" about 10 seconds and begin repeating itself. The video continues on. After about 10 seconds of this, the audio will cut out for a few seconds, then come back synchronized. The audio will stay synchronized for another 5-7 minutes, then the same thing will happen again.

It doesn't happen while watching live TV or the Netflix app, and it doesn't seem to happen with on-demand other than MHz choice.  There are never problems with video.

Comcast support tried resetting the box etc, but it didn't help. So they sent out a new X1 box. I installed and activated the X1 box, but the problem immediately recurred.

Any ideas?  If we can't fix this we'll have to cancel the MHz subscription and watch it with something else.

I am experiencing the exact same audio desync problem with MHz Choice, which I recently subscribed to through Xfinity.

I also called Xfinity tech support and they reset the cable box and tried some other diagnostic fixes. The problem continues. I do not need a new cable box as the issue only occurs with the MHz Choice content.

I then contacted tech support at MHz Choice, but was informed they could not help if my subscription was through Xfinity. They suggested I cancel the subscription through Xfinity and resubscribe directly with MHz choice and use a Roku, Firestick or Apple tv device for streaming.

Xfinity needs to resolve this issue if they want to keep offering MHz Choice on their platform.

So we're just cancelling our Xfinity MHz subscription, subscribing direct with MHz, and watching on a $30 Chromecast.

On the whole it's a plus. The MHz iPad app is easier to use than navigating through the X1 remote, and the picture is sharper since it doesn't pass through the X1 smoothing filter (or whatever the X1 does to skin textures).

Very occasionally the stream goes to a lower resolution, but otherwise we're not looking back.
