H9-2S Brief freeze

[davidja]

Watching satellite based terrestrial TV - I had Wooshbuild Infinity on my Zgemma and started to experience a brief freeze in the picture then it sped up to catch up, all the time the sound was unaffected. I assumed it was the OPenATV version so updated that and no change. I have now replaced Wooshbuild with latest Openvix and STILL experience the identical problem. The box is less than a year old at most surely it cant be faulty? Any advice appreciated.
