I recently received my h10-250 HD-Directivo. I have set up the over the air portion of it but I am having a weird problem. I don't know if anyone else on this board lives in Abilene, Texas that can confirm this. Channel 29 the local NBC affiliate is stuttering. The best way I can describe it is that it plays for a second pauses then plays for another second and repeats continuously. My signal strength is in the upper 80s lower 90s. My other OTA channels are working fine. Any ideas?
