I purchased the Actiontec MoCa adapters (HME2200-02K) and they work great. I installed the coax filter from ChannelMaster (PCTLPF1002) to isolate my network from the cable company and outside world. Since installing the filter I noticed glitches in the TV picture. Notable pixelation. I thought it was my imagination. This morning I took the filter off and the picture seems fine again.
