[Skunkworks] "Nenda"TV decoder

Hi guys, Just noted that most channels on the now popular decoder have very poor quality pictures. Where could the picture quality be getting lost? Additionally the popular decoders are not HDMI capable. What could be the remedy coz I do not think that this is the digital migration we wanted. Are the other FTA decoders in the market with HDMI ports any better? Kindly share your views/observations. Warm Regards, Jeff
