I would say ESPN has really improved their picture quality immensely compared to 2010. The networks of ESPN were godawful at the start of football season that year. By the end of the 2010 football season,ESPN took strides, then I think ESPN switched their encoding from MPEG2 to MPEG4 sometime in 2011 and I would say the picture quality has been great since that transition. I would say 95% of live sports programming on those networks, the picture quality is good (seems to be an occasional clunker on ESPN U, but that is about it). With Fox as a previous poster said, you never know what you'll get. With Fox's OTA affiliates and O&O stations, they use that splicer which caps the main Fox feed to about either 12 or 13 mbps so that the stations can use the remaining bandwidth for subchannels. I think the way Fox uses their HD programming technology is not a good one as it should be left to the affiliates to determine how much bandwidth is used for their channels. At least with affiliates having that option, they can flex the bandwidth when major sporting events come on.
