Yes, I certainly did. ALL channels were stuttering and pixelating about every 15-20 seconds. No exaggeration! Obviously, too annoying to watch anything that way. I had a 92 signal at the time. I first noticed this while watching CH100 News. Then out of curiosity, checked all the VOOM exclusives as well as DiscoveryHD and various SD channels. All had the same thing going on. Sorry, but I don't remember the time. I was just going to forget it until I saw your post.
I read the posts about tuning to a strong OTA, etc. I don't have OTA into the VOOM receiver. I don't use a diplexor. So those things weren't affecting my picture. I put the OTA feed directly into my TV as it works better that way. (The TV has a built in HDTV tuner)
I did all the things like the red button and hard and soft reboots. I hate to do these reboots as the PG takes so damned long to reload. Anyway, nothing helped so I just turned the TV off and worked in the shop. I haven't tried it yet today. I'll post if it is still doing this today.
