I had a new problem appear tonight on both of my MPEG4 channels (ABC and FOX): audio stutter. It is listenable, but highly annoying (unlike the snapping and popping which is both unlistenable and annoying). MPEG2 and SD don't have the problem. I don't know if this is a D* encoding issue or an HR20 playback issue; I do know it is D* issue because my OTA receiver (media center PC) did not have this problem. Maybe the new software will fix the problem or just new encoding? Has anyone else had this problem? Has anyone in LV watched FOX or ABC today and NOT had the problem?
