Advertisements Full question: Do cable operators (ie Comcast) re-compress some or all channels? Example 1: Taking a OTA HD channel and increase the the compression so that the video quality is lower than what is received OTA Example 2: When I watch a rerun of some TV show, such as "Friends", on a cable channel, the video quality is noticeably lower than the video quality when streamed from netflix, hulu, etc. Example 3: HBO and other pay channels all have high quality video than other channels, and local OTA channels have the lowest quality. I am trying to understand if these differences in video quality is based on decisions made by cable operators, or are they just "passing-through" the video quality they receive from the source. I am assuming that the my Bolt is writing the channel stream directly to the HDD without processing it in such a way that would lower the video quality.
