I just recently entered the HDTV world and I am generally very happy with the results. However, I have noticed that during high-action sequences in films(especially on HDTMN), that the picture pixellizes or even hiccups. I also have noticed that if there is an intense red colour on-screen that there is pixellization as well. The regular 480 res channels are fine. I had a technician come in to check my setup. He changed the splitter I had and the coaxial cable going into the STB from the wall outlet. No change. Should I move to using a DVI connection from my STB? Should I replace the STB? ANy suggestions?

The folks at TMM-HD advise that this is a known problem at present due to the excessively low bit rate available in the cable systems for the TMM-HD channel. It is compression macroblocking. A fix is in process of development and will remove much of this problem. Rest assured, it is not a problem with your HD television, your set top box or with your connections.
